In the Autobot base, Prowl and Serenity were practicing dodging assembly line. Both making it to the end, while Harvest and Sari watched. 

"Awesome!", Sari cheered, while on her roller blades. "Now, let me at that thing.", Sari said. 

Serenity then gave a unsure look. "I'm not sure, Sari. You could get hurt.", Serenity said. 

Prowl then added, "It's harder than it looks. Let's try it at one quarter speed." Sari did a few air punches, as her helmet fell over her eyes. 

"No way! I can do it just as good as you two... Blindfolded.", Sari said. Serenity lifted up her helmet, as Sari smiled at her and skated over to the assembly line. 

Struggling to get up, Prowl then helped her. Serenity stood next to Harvester. 

"You want to try?", Serenity asked. Harvester then shook her head. 

"N-No thanks. I think I'll just watch today.", Harvester replied. Serenity nodded and turned her back to Prowl and Sari. 

"When you make it to the end, then you can advance.", Prowl said. "Ha! Piece of cake. Watch the master! Uh... Misterius... Uh... Never mind.", Sari spoke, confidently. 

Serenity laughed at the young girl's antics. Sari was soon in place. 

A moment of doubt came over her, as she headed into the assembly line, getting wacked by the first arm. Serenity rushed over, before she could hit the ground and grabbed her landing on her back with Sari in her arms. 

"No fair! This game cheats!", Sari whined. Prowl chuckled, as he picked up Sari by the cuff. 

"With time and patience, you'll improve.", Prowl said. Then, the sound of dripping caught everyone's ear and Bulkhead came shushing. 

"What is that? Something's dripping!", Bulkhead shouted out, as Prowl, Serenity, Sari, and Harvester shrug. Bulkhead then looks around for the source to find Bumblebee's hand dripping oil. 

"You!", Bulkhead continued. He then went over to Bumblebee and picked him up. 

"Stop leaking! You're frying my circuits!", Bulkhead shouted out. "What?", Bumblebee asked, confused. 

Ratchet then used his electric power to pull Bumblebee over to him. "Looks like someone needs a tune up.", Ratchet said. 

"What? I'm perfectly fine!", Bumblebee said, waving his arm around, as oil fell. Ratchet then gave a gross look. 

Optimus then came into the room. Both him and Serenity sharing a look, before he went over to the rest of the team. 

This didn't go unnoticed by Sari. She then turned to Bumblebee. 

"Oh, Bumblebee! You make my hardwired go nuts!", Sari said in a fake tone. Bumblebee caught on. 

Still stuck on Ratchet, Bumblebee said, "Oh, Sari! How could I ever live without you?" Serenity and Optimus made a confused face. 

They then continued. "Bumblebee, will you accept this bolt I found on the ground to be a symbol of my love?", Sari teased, as Serenity rolled her eyes. 

"Why yes, Sari. Please, marry me now.", Bumblebee stifled a laugh. "Okay, you two! Knock it off!", Serenity said, as she moved closer to Optimus, who picked up the remote. 

"I just picked up this broadcast on the monitor. Looks like Mix Master and Scrapper are back and up to their old habits.", Optimus explained. Harvester then shuddered, remembering the last time she saw her adopted brothers. 

And how they had tried to force her to join the Decepticons. Bulkhead moved closer to her and he put a comforting hand on her shoulder. 

And, as Harvester snuggled into the gesture, Bulkhead's face plates start heating up. "Chaos erupted downtown. When two giant robots wreaked havoc at Marombo's Brother's Auto supply, the robots made off with 100 cases of motor oil, before evading police by what appeared to be a smoke screen.", the news reporter said. 

It then showed pictures of the two said robots. "We have to find them before Megatron gets a hold of them.", Optimus said, turning off the TV. 

"Do you think they'll remember us?", Bulkhead asked. "Doubtful. After those two malfunctions. No offence, Harvester. Lost their memories, they forgot everything. Except how to guzzle oil and be obnoxious.", Ratchet spoke up. 

He then sent a sympathetic look at Harvester. "Well then, we better hurry. Because they're halfway to being Decepticons already.", Bumblebee said, as Ratchet ran off with him still hooked onto his hand. 

Sari and Harvester started to follow. But, Optimus stopped Harvester and Serenity stopped Sari by putting her hand in front of Sari. 

"Hey!", Sari protested. "No. Not this time, guys.", Serenity said. 

"They nearly took Sari's head off and kidnapped you, Harvester.", Optimus added, letting the little femm bot go. "And that's when they were trying to be friendly.", Optimus and Serenity said at the same time. 

They looked at each other and blushed, before turning away. "Ugh! Why don't you just marry her already?", Sari whined, as Serenity transformed and headed out with the rest of her team. 

"And I can totally take care of myself. Remember when I kick that barnacle monster's butt all alone?", Sari said. Harvester then spoke up. 

"And I helped Prowl take down Lockdown... Okay, maybe not exactly like that. But, I have learned how to defend myself since then.", Harvester added. Optimus smiled at the two. 

"True. But, a human child is still no match for a two story robot.", Optimus said. He then turned to Harvester. 

"And Bulkhead would never forgive me if anything happened to you, Harvester. Keep Sari safe.", Optimus continued. He then left with the rest of the team, leaving the two behind. 

But as they left, Bumblebee was still leaking oil, leaving a trail behind. "So, what's going on with you and Bulkhead?", Sari asked, trying to start up a conversation. 

Harvester began to blush madly. "W-We are f-friends.", Harvester stuttered. 

Sari smirked and went over to sit on her cushion. "I can't believe they just left us here. I mean, we are vital members of the team! How can they find those construction bots without my key? And how can they convince them to come back with us without you? I mean, they might remember you. No, we're stuck here all alone... We're stuck here all alone...", Sari said, as her mind racing with mischievous ideas. 

"What are you thinking?", Harvester asked. Sari went over to the vending machines. 

Using her key to make a bunch of candy to come out. Harvester then looked horrified. 

"You're going to get sick from eating all that.", Harvester said. "It's our small rebellion. Come on! You can admit that you're mad they left you behind, too.", Sari told her. 

Harvester then looked away. "I suppose...", Harvester mumbled. 

She looked over at Ratchet's tools. Sari followed her gaze. 

"Aren't those Ratchet's special tools?", Sari asked, as Harvester walked over and grabbed one. "Yep.", Harvester replied. 

Later on, Sari hooked herself to one of the arms on the assembly line and gave Harvester the thumbs up. Harvester then turned it on, as it started spinning her around. 

Faster and faster. Harvester stopped it when she saw the candy that Sari ate make their return trip. 

Sari then put on her helmet. "If Prowl can do it at full speed, then so can I.", Sari said. 

Harvester looked at Sari then at the assembly line. "Besides, the fact that he has been trained his whole life on these sorts of things.", Harvester added. 

Sari gave her a deadpan look. "Are you going to turn it on? Or end the rebellion here and now?", Sari asked. 

Harvester turned on the assembly line. "If you get hurt...", Harvester said. 

"I won't! Don't be such a worry bot.", Sari cuts her off. She then got started. 

Sari was actually doing really well, until the end where one of the arms hit her from behind. Meanwhile, the rest of the team were still looking for the Constructicons. 

Bulkhead still getting annoyed by Bumblebee's leaking. "Will you plug it already!?", Bulkhead exclaimed. 

He then brought out his arm and put a sticker on Bumblebee's hole. "Much better.", Bulkhead continued. 

Optimus had been driving unusually slow. This didn't go unnoticed, however. 

"Optimus? Are you okay?", Serenity asked, while driving up to him. Optimus was startled by her sudden proximity. 

"Y-Yeah! I'm alright!", Optimus replied. Serenity then slowed down to where Optimus was in the lead again. 

Soon, Prowl drove up next to him. "What are you thinking about, Prime?", Prowl asked. 

Optimus knew he could tell Prowl. "It's about what Sari said. Me and Serenity have become close... I-I would like to propose to her.", Optimus replied. 

Prowl was silent for a minute. "I think you should.", Prowl said. 

"But, what if she doesn't feel the same way?", Optimus asked. "She loves you, Optimus. You've heard it yourself.", Prowl replied. 

"But, that is when she remembered me fully. What if-", Optimus said. "Optimus, let me ask you something.", Prowl told him. 

Optimus waited for the question. "Do you, Optimus Prime, promise to love and care for Serenity as long as you live? To cherish her in sickness and in health? Refusing all others?", Prowl continued. 

"Yes.", Optimus replied. "Then, what does that tell you, Optimus?", Prowl asked. 

Optimus remained silent. "Thank you, Prowl.", Optimus said. 

Elsewhere... "About time we ditch the cops, Mix! Now what do we do?", Scraper asked, while burping. 

Mix looked at something on the ground. It was a trail of oil. 

"Yo, Scrap! Check it out! Oil...", Mix called out. He then leaned down and tasted some. 

"Ain't the sweetest grade I've had. But, good enough. I just wish I could remember where we got that really good stuff. Come on, there's got to be more around here someplace.", Mix continued. So, they followed the trail. 

Megatron watches the news report. "It appears our Constructions have resurfaced.", Megatron said. 

"Perhaps with their help we can finally finish building the space bridge.", Icy Blitzwing said. "Find the Constructicons and bring them to me immediately! The signal dampeners we outfitted them with should prevent our enemies from tracking them. But, do not engage the Autobots!", Megatron ordered. 

Megatron then handed a can of oil to Blitzwing. "This should lure them out. Now go!", Megatron continued. 

Soon, the Constructicons were at the base. Sari and Harvester were unaware, as they both listened to some music. 

"Great! How do we get past the door?", Scraper asked. "Forget about it! I'll just mix up my own door.", Mix said, as he mixed up a solution that melted the door. 

"Now, that's what I call a door.", Scraper said. As the Auotbots drove, Bumblebee saw a mixing vehicle. 

"It's Mix Master! Let's get him!", Bumblebee yelled out, while transforming his hands into the stingers and hitting the vehicle. A man then leaned out the window. 

"Dude! Why are you ramming up my truck?!", the man yelled out. "Sorry, I-I thought that you... He... Uh... Your... Uh... Truck was someone else.", Bumblebee said. 

Bulkhead then put a hand on Bumblebee. "That oil leak really frazzled your circuits. Didn't it?", Bulkhead said. 

"There is nothing wrong with me! I'm at 100% in tip top running condition.", Bumblebee said. Then, Bumblebee's sticker came off, as more oil fell out. 

"Yo, Mix! Something gives me the creeps about this place. Like, we have been here before and it didn't end too good. Know what I'm saying?", Scraper said. "I don't know. It feels familiar, but whatever. Let's throw back a few barrels of oil and then beat it.", Mix Master said. 

Sari then started racing down the hall. "Come on, Harvester.", Sari said. 

"I'm coming! Just wanted to put Ratchet's tools back.", Harvester said. "What's the point of the rebellion if you aren't going to let them know you were rebelling?", Sari asked. 

"I'm rebelling on the inside. I don't want to end up with a wrench to the head from Ratchet.", Harvester told her. Then, she heard Sari bonk something. 

Walking inside, Harvester saw Sari with her adopted brothers. Fear stopped her from moving, as she thought about her time with them. 

"So, you know where we can grab some motor oil around this joint?", Mix asked Sari. But, Sari didn't answer. 

She just let out a high pitched scream. "It's trying to pry our audio circuits!", Scraper yelled out. 

"What?! I can't hear yas!", Mix asked. "I knew there was something up with this place. This must be the runt that messed us up last time.", Scraper said. 

"What? This whinny little thing?", Mix asked. Harvester was finally knocked out of her fearful state when she saw Mix about to grab Sari. 

She rushed in and grabbed her, before Mix did. But, Mix hit her ear piece, knocking off her comb. 

She then then brought Sari to safety, as she looked at her brothers. "So you two joined up with the Decepticons after all.", Sari said, placing her key in the wall, as a door came slamming on top of Scraper. 

Harvester winced slightly for him. Sari and Harvester then made a run for it. 

"Mix! Mix! Get me out of here.", Scraper called out. "Quit your whining, you big nail clipper!" Mix said, as he pulled him out. 

"I told you that little thing was trouble, Mix. And now she's got a robot helping her. What do you think a Decepticon is?", Scraper asked. "Who cares? That little screaming mutt and puny encomium model is definitely hiding some premium oil in this joint! We got to follow them.", Mix said, while upside down on Scraper. 

Scraper then stood up, as Mix fell off him. "Follow them! That's probably how we got our memory circuits scramble in the first place.", Scraper said. 

Mix then hit Scraper. "What's the matter with you?! You're an excavator! Not a goft cart! Grow a back and let's get some oil." Mix told him. 

Back with the Autobots, Prowl was watching everything from up on the roofs. "No sign of Mix Master, Scraper, or the Decepticons.", Prowl said. 

"Any luck on your end, Bulkhead?", Optimus asked, though the comms. "No sign of-", Bulkhead replied. 

He then saw a jet fly over. "I just spotted Blitzwing.", Bulkhead continued. 

"Are you sure?", Optimus asked. "Pretty sure... Kind of...", Bulkhead said, uncertainly. 

"This is pointless without Sari and her key. We can't track their signal. And has anyone thought how we are going to convince them to come back with us without Harvester?", Bumblebee asked. "They're safer at home, Bumblebee.", Serenity and Optimus said at the same time. 

"Man, you two really are meant to be a couple.", Bumblebee said. Back at the base. 

"Oh no! Oh no! Oh no!", Sari and Harvester repeated, as they ran through the halls. Sari then stopped by a wall, holding her stomach. 

"Wow! I ate way too many candy bars.", Sari commented. Then, they heard them coming closer. 

"Come on!", Harvester said, as she picked up Sari and ran. The rest of the team were meeting in a parking lot. 

"Okay! So, no one saw anything out of the ordinary?", Optimus asked. Everyone shook their heads. 

"We'll never find them at this rate. I'm going to call Sari and Harvester.", Bumblebee said, as he pulled up his comm. Meanwhile, Sari was hiding in her bed and Harvester was holding onto a beam on the roof. 

"Ah! No oil in here.", Scraper said, looking around. But, just as he was leaving, Sari's phone went off. 

Scraper picked it up and it started falling from his grasp and Mix threw it on the ground. "Quit fooling around! Let's find some oil!", Mix said. 

Harvester let out a small cry, as the phone crunched, worrying that might be her or Sari. After they were gone, Harvester pulled up the blanket that Sari was hiding under. 

Only to find her growling. "It's just a phone.", Harvester said. 

That just made Sari growl more. Back with the rest of the team. 

"Autobots! I will crush them into iron filings!", Hothead yelled out, as he began his descent. "But, my orders are to find the Constructions.", Icy said. 

"Ooo! But, I like iron filings! Especially sprinkles on top of servo salad!", Random said. "Sari is not picking up her phone.", Optimus said. 

"And Harvester isn't answering her comm either.", Serenity added. "You think they are okay?", Bumblebee asked, slightly panicking. 

Before anyone could answer, they saw Blitzwing heading for them. "We're not! Take cover!", Ratchet yelled out. 

"I told you it was Blitzwing!", Bulkhead stated, as Prowl pushed him out of the way. "Now, I'll have to call Prime and the others from the communication center out there. But, by the time they get here, those tow oil guzzlers will wreck the whole place.", Sari spoke to Harvester. 

"We can multitask.", Harvester suggested. "This is our house and we are going to defend it. We'll show them we are just as tough as they are.", Sari said. 

"Yeah!", Harvester cheered. She and Sari then high five. 

Harvester silently thought, 'And maybe I could get my brothers back...' The rest of the team raced from Blitzwing, as he shot at them. 

"We need to keep moving. Find a safe area to engage him. We need to get him away from downtown. It's too crowded with humans.", Optimus ordered. But, they all came to a stop when they saw the traffic jam. 

"Maybe you should tell them that.", Ratchet grumbled. "Are my circuits still on the fritz or did we just drive into the middle of a parking lot?", Bumblebee asked. 

"It's not the stopped vehicles I'm worried about. It's the moving ones.", Prowl pointed out, as Blitzwing grabbed two gas tankers. "You wimpy malfunctions are going offline!", Hothead shouted out, as he threw the tanks at them. 

Ratchet then used his magnetic powers to stop them. But, they pushed him into a wall. 

"Nice work, Ratchet! You, Bumblebee, and Serenity clear the humans out of harm's way. The rest of us will hold off Blitzwing.", Optimus instructed. "Clear them where?", Bumblebee asked. 

"I got an idea.", Serenity said, as she went to the vehicles. "I need you all to head away from the fights. I will provide a shield for you. But, move in an orderly fashion.", Serenity continued, as she put her shield up. 

"Ratchet, Bumblebee! Help them move.", Serenity said. "Oh, I'll keep him distracted. He always shoots at me first.", Bulkhead stated, as he gets his wrecking ball ready. 

"Let's see how tough you are without your bot brain bruiser!", Hothead shouted out, shooting at Bulkhead. As the Bulkhead fell down. 

"Called it.", Bulkhead continued. At the base, Sari and Harvester got ready to defend the base. 

"Look at this shoddy construction! What knucklehead slabbed this junk together?", Mix said, through a couch. Scraper then moved over to the TV. 

"We need a plan.", Harvester stated. But, Sari wasn't paying attention to her. 

"You broke my cell phone! But, you are not going to break my TV!", Sari shouted out. She then ran out and hit Scraper with her hockey stick, breaking it. 

"Okay, that is as far as my plan got.", Sari continued. Harvester then hit Mix in the back, distracting him for Sari to run, soon following her. 

"What the front end loader was that?", Mix asked. As they started to chase them, they saw the girls go hide in one of the rooms. 

"You don't get away that easy, you little gremlins!", Mix stated, as he chases them into Prowl's room. But, found no one. 

"They must have ran into a different door.", Scraper summed up, as they leave. Not realizing that Sari was behind the tree and Harvester was up in the
