In Detroit, Optimus and the rest of the Autobots were repairing the city. "This is a big clean up job. Even for a bunch of maintenance bots like us.", Bulkhead complained. 

Meanwhile, a bunch of cars were stopped at the road block. One impatient lady honking her horn. 

"One moment, mam.", Optimus said, as he transformed and lifted to rock. He was blocking the path and looking quite scary, as he did so. 

"Please don't hurt us!", the frightened woman exclaimed, before turning around. The other cars following, too. 

"Those humans were afraid of me.", Optimus said, sadly. "Can you blame them? After all we did trash half their city.", Ratchet said, angrily. 

"I believe the Decepticons did most of the trashing.", Prowl pointed out. "I liked to better when we were heroes.", Bulkhead said, as he sat down. 

"We are still heroes, Bulkhead. We just have to remind them.", Optimus encouraged. "Like how we have to remind Serenity.", Bulkhead added. 

Optimus then looked down at his peds at the mention of the princess and love of his life. "She will remember you, Optimus. Just give it time.", Prowl encouraged, putting a comforting hand on his leader. 

Optimus tries to smile, but found that he couldn't. "Let's... Get back to work.", Optimus said, sadly. 

Ratchet then seemed to notice something. "Hey! Where is Bumblebee and the princess? Aren't they suppose to be helping, too?", Ratchet asked them.

At Sumdac tower. "Isaac Sumdac's office, please hold. Isaac Sumdac's office, please hold. Isaac Sumdac's office, please hold.", Bumblebee repeated, as he took calls and carried papers around. 

"Isaac Sumdac's office. No, Isaac Sumdac still hasn't returned from his extended vacation. Of course, someone is running the company. Someone very capable.", Bumblebee continued. Serenity, meanwhile, was going through video footage and trying to find the Decepticon signals, thinking they may be responsible for Sari's missing father. 

"Ugh! No wonder my dad acted so crazy! How do you do this?!", Sari cried out, in frustration. Then, Porter C. Powell appeared on the screen. 

"Ms. Sumdac, as chair man of your board of directors, I've been going over the books and I see your still wasting valuable resources searching for your missing father. Isn't it time you just accepted the fact that he-", Powell stated, but was cut off from Sari slamming her fist into the table. "No! He's my dad! And if I were missing, he would do the same for me.", Sari told him. 

"Young lady, there's no room for sentiment in business. A mere child can't be trusted to make some decisions for this company.", Powell scoffed. Serenity then looked up from her work to her struggling young friend. 

"This company's name is still Sumdac! And until it isn't, I'm staying right here and there's nothing you can do about it!", Sari yelled out. Powell then turned off the screen. 

"That's telling him, Sari.", Serenity encouraged, while smiling. Sari tried to return the smile, but it didn't last long. 

Serenity then moved up from her place and walked over to Sari, putting a comforting hand on her back. "Hey, Sari. We will find him.", Serenity reassured her. 

"Yeah... Hey! How are you and Optimus?", Sari asked. "You mean the Prime? Well, I notice he has great leadership abilities.", Serenity replied. 

"So, you don't remember anything about him?", Bumblebee asked, while putting some of the paper down. "I don't.", Serenity replied. 

"What about when the boss bot and you fought against Megatron?", Bumblebee asked her. "I know someone was there, but it's fuzzy. I can't remember the details or who I was with. I remember you guys. But, when it comes to the Prime... I draw a blank.", Serenity answered. 

Bumblebee and Sari both looked at each other. "What do you think caused that?", Sari asked. 

Before Serenity could answer. "You might want to take a look at this.", Bumblebee stated, as he pointed at the TV where it showed something was heading for Detroit. 

"All eyes are in the sky, as a mysterious, unidentified object from space entering Earth's atmosphere is heading straight for downtown Detroit.", a reporter bot said. Optimus and the rest of the Autobots where also watching, as it soured over them. 

"Did you guys see that?", Bumblebee asked, as Sari and Serenity followed. "Kinda hard to miss.", Ratchet pointed out. 

"We better look into it. Transform and roll out.", Optimus commanded, as they started heading for the object that they now realized was a spaceship. The captain and his police force were already there.

"Okay, secure the perimeter! We're not taking any chances with this one.", Fanzone ordered. Optimus then walked toward the captain.

"Have your men stand down. Let us handle this.", Optimus said. "So you can wreck the other half of the city? I don't think so!", Fanzone told him.

As the ship's doors open, everyone waited in anticipation. There stood Ultra Magnus, Jazz, and Sentinel.

"Robots... Why did it have to be robots?", Fanzone complained, as Serenity, Optimus, and the others came forward while saluting. "Ultra Magnus, sir. Welcome to Earth, Commander. It's an honor-", Optimus tried to said, but was cut off by Ultra Magnus.

"Jazz, set up a force shield to quarantine from those organics.", Ultra Magnus ordered. Jazz then looked past the Autobots to the humans standing nearby.

"You sure that's necessary, Commander? I'd like to get a closer look.", Jazz said. "You might feel different when the slime they spew out melts through your armor plating and rots you circuits from the inside.", Sentinel warned him.

"Really?", Jazz asked him. "I've had some experience with organics. And believe me nothing good can come from contact with them. Isn't that right, Optimus? Serenity?", Sentinel replied.

He then wink at the princess, as Sentinel brought down the shields. Sari then ran to the force field and tried banging against it.

"What's the big idea?!", Sari shouted out. "Sentinel Prime, decontaminate Optimus Prime, the princess, and his crew.", Ultra Magnus commanded.

"With pleasure, sir.", Sentinel said, as he walked up to Serenity, but kept enough distance to where he wouldn't get 'infected'. "Miss me, Sweet spark?~", Sentential purred.

Serenity didn't answer, but turned her attention to the new bot, Jazz. "Jazz? Is that you?", Serenity asked.

Jazz walked up and gave Serenity a hug. "Yes it is, Crimson.", Jazz answered.

"Crimson?", Bulkhead asked, confused. "It was her nickname while at the dojo. It was the name of a blade she used.", Prowl answered.

"I thought you stayed with the dojo. What are you doing in the Elite Guard?", Serenity asked. "I'll tell you on the way to the ship.", Jazz said, as he linked arms with her and walked in.

Sentinel was glaring the whole time. "Hey, Serenity! How about I give you a tour later?", Sentinel called out, trying to get her attention.

"Maybe.", was all Serenity said, she walked with Jazz. "Great. Jazz get to go with the princess, while I'm stuck with the Elite Guard drop out and a bunch of rust buckets!", Sentinel complained, as he got the washer ready, spraying them harshly which seemed to lighten his mood.

Meanwhile, Jazz had allowed Serenity to use a private shower, since she was the only fen men, as he waited outside. "So, I decide to put my time as a student to use and train others in the Elite Guard.", Jazz finished his story.

"I'm glad for you, Jazz. Yokatron would be proud.", Serenity said. Jazz then smiled.

"So, how have things been with you and OP?", Jazz asked her. Serenity didn't answer, however.

"Serenity? Are you alright? Did something happen?", Jazz asked, concerned. "Yes, but I don't want to talk about it right now.", Serenity replied.

Jazz didn't want to push her, though. "Did he do something to you? The way you use to talk about him, I thought-", Jazz asked her.

"He didn't do anything. At least, I don't think he did. Can we talk about this later, please?", Serenity answered. Jazz didn't want to push her any more, so he dropped it.

"Alright. I better make sure SP isn't driving the others too bad. And the commander want to talk to you.", Jazz said, before he left. Back with Optimus and the others, Sentinel seemed to be enjoying himself by spaying them.

"You! Tiny! Step out from behind your overgrown pal!", Sentinel ordered. Bumblebee then stepped out from behind Bulkhead.

"I don't think he remembers us.", Bulkhead whispered. "And that's just the way I want to keep it.", Bumblebee answered, as he was sprayed close to the face.

Optimus stood in the front, a sad expression on his face was quickly covered by a spray of water. "This is completely unnecessary, Sentinel.", Optimus said.

"Can't risk an infestation, old buddy! Take it like a real bot!", Sentinel told him. Jazz then came over and turned off the water.

"Cool it, Sentinel! Whatever happen between you and Optimus, you don't need to harass his crew.", Jazz scolded him. Serenity then walked up to her uncle.

"You wanted to see me, sir?", Serenity asked, trying to hide the edge to her voice. "Is something wrong, My dear?", Ultra Magnus asked, as he walked down and lifted her chin, as a father would do to a daughter.

Serenity soon pulled her face away. "I know...", Serenity said.

Ultra Magnus seemed too anxious at this. "Know what?", Ultra Mangus asked her.

Serenity then decided to let it all out. "Who murdered my mother, who my father is, and what I am!", Serenity yelled out.

"Why didn't you tell me that Cyclonus killed her? I had to face him myself!", Serenity continued. Ultra Magnus was startled at this.

"You what?!", Ultra Magnus exclaimed, shocked. Serenity then showed him the scar.

"Why didn't you tell me my father was the Fallen? Why didn't you tell me I was experimented on?!", Serenity yelled out. She then covered her face and started to cry.

Ultra Magnus went forward and started to hug her, letting her get all her tears out, before she spoke. "I'm sorry, My child. I thought I was doing the right thing, at the time.", Ultra Magnus said, calmly.

Serenity didn't speak, but she didn't turn away from the hug either. They both stood like that for a while. 

"I know you wanted to protect me. But, why didn't you tell me?", Serenity said, as she pulled away and looked into her uncle's face. "When the war broke out, many young bots at the time lost their innocence and their will to live, thinking there was no possible future. Cybertron needed a leader who could moved beyond the tragedy of the war. I didn't want you to have to deal with...", Ultra Magnus trailed off, thinking about the death of his sister. 

He was close to losing his will to live when his twin sister died. It was Serenity who made him want to live again. 

Sensing his inter turmoil, Serenity pulled closer bringing Ultra Magnus out of his thoughts. "I was going to tell you, my dear niece. But, part of me was afraid to. That I would lose the one I had come to love as my own sparkling.", Ultra Magnus continued. 

Serenity then hugged tighter. "You won't lose me, but I need to know about these things. It's part of the trust between a sire and sparkling.", Serenity told him. 

Ultra Magnus then smiled. She had called him a sire.

Meanwhile outside, Sari was trying to convince the captain to get the others out. "They're trapped! Held against their own will! You got to get them out!", Sari shouted out. 

"I ain't about to provoke a intergalactic incident.", Fanzone told her. "I tried to clean them up as best as I could. But, you know how it is with these grease grunts.", Sentinel claimed. 

He then turned to look at Serenity, who was glaring at him. "All except for the princess.", Sentinel purred. 

Serenity then rolled her eyes and walked over to her team. "That will be all Sentinel Prime! We've wasted enough time and valuable resources tracking down these stragglers.", Ultra Magnus said, turning to look at Optimus and Serenity, who was standing by him. 

"If it's all the same to you, we'll just retrieve the Allspark and the princess, then be on our way.", Ultra Magnus continued. They all looked at each other uncertainly, especially Serenity. 

She didn't want to leave Earth. Serenity wanted to regain her memories of Optimus. 

It was obvious they shared something special. She wanted to know what it was. 

Bumblebee then started to talk. "Yeah! A-About the Allspark... Long story... It kind of sorta...", Bumblebee said, nervously. 

Bulkhead soon finished his thought. "Blew up!", Bulkhead said. 

Serenity then face palmed, as she saw the looks on the crew's faces. "What!? The Allspark is destroyed?!", Ultra Magnus asked, angrily. 

"Not exactly destroyed, Sir. More like it's energy was dispersed. At least I think it was.", Optimus quickly covered up. Ultra Magnus then looked at Serenity. 

"And what do you remember of this?", Ultra Magnus asked. Serenity then kept her head low. 

Optimus wanted to help her, but was afraid of over stepping his bounds. "I... I don't remember it.", Serenity replied. 

"What?", Ultra Magnus asked her. 

"When the Allspark was... dispersed, it scrambled some of my memories.", Serenity explained. "If I may ask, which memories?", Ultra Magnus asked. 

Serenity then looked at Optimus. "Memories of me.", Optimus finished for her. 

Sentinel soon smirked at this. "You have made some big time blunders in you day, Optimus. But, this one tops them all.", Sentinel said. 

"He's a slaggin hero for keeping it and the princess away from Megatron and the Decepticons!", Ratchet defended. Serenity wished so bad she could defend Optimus. 

If only she could remember, she would rather support him than Sentinel. Just from the little while Serenity had known him or at least the little while she remembers. 

"Stand down, Rust bucket. Your boss is a lot of things and hero isn't one of them. How about a mind washer?", Sentinel told him. Serenity then had enough. 

"I may not remember Optimus. But, so far what I have seen of him is that he's a great leader and has a loyalty to his team, thinking of them first before himself! Something I don't see much in you, Sentinel.", Serenity said. She continued to glare at him, while Optimus felt a warmth in this spark. 

Sentinel then pretended to be wounded. "That hurts, Sweet spark. And besides, I don't always think of myself. A beautiful femn has been on my mind recently.~", Sentinel purred, blowing a kiss to Serenity. 

It took all of her will power not to gag at this. "And we did a sweep of the entire planet. Not one trace of Decepticon energy signatures.", Sentinel said, getting up in Optimus' face.

"Because we kicked their sorry solenoids!", Bumblebee yelled out, stepping beside Optimus. "You expect us to believe that a bunch of glitch detain flunkies could defeat Megatron?", Sentinel sarcastically asked. 

He then looked at Serenity. "And the only reliable witness, the princess, can't remember. She shouldn't even had been at that fight if it happened. We can't have our future queen getting herself hurt.", Sentinel continued. 

Serenity soon growled lowly. "Why do we hide here like cowards?! We should stand and fight the accursed Autobots!", Lugnut shouted out, as his arm fell off. 

"Patience, Lugnut. These carbon deposits shield us from detection, while we recover from our last encounter with the Autobots and princess. Besides, I have set on a far bigger prize, Cybertron itself.", Megatron said, as he brought up a picture of their home planet. "That sounds crazy even to me.", Random Blitzwing said, as Lugnut hits him. 

"How dare you doubt the word of our glorious leader! But master, how will you pull off this stunning victory?", Lugnut asked, as he struggled to put his arm back on. "Two things led to our defeat during the Great War. The Allspark and the Autobots' exclusive space bridge technology. The Allspark, as we know, is no longer a factor. But, during my battle aboard the Autobot ship, I was able to download a schematic for one of their space bridges.", Megatron said, as he pulled up the computer. 

"Intriguing. If we reverse engineer the technology, we could build our own space bridge.", Ice Blitzwing stated, as he turned to Hothead. "And beam ourselves to Cybertron and conquer the planet from within!", Hothead continued. 

"There is just one glitch. The specs are incomplete. We will need assistance in filling in the gaps and who better than to assist than the master of reverse engineering? Professor Isaac Sumdac.", Megatron said, while turning to the cell he kept the professor in. "You cannot trick me into helping you this time, Megatron. The Autobots and princess will come for me.", Mr. Sumdac told him.

"And yet this they have not. Why do you think that is? Would it have something to do with the fact that you resurrected their worst enemy?", Megatron asked, while smirking. "Right now the only thing keeping you alive is your usefulness to me.", Megatron continued.

Back at the ship. "I'll give you points for creativity on your bogus story, Optimus. But, where's your proof? Show me one shred of evidence that the Allspark wasn't completely destroyed on your watch.", Sentinel said, as he marched in front of the team. 

But, that wasn't the main thought on his mind. 'With Serenity's memories scrambled, I can make my move. Optimus doesn't stand a chance now...', Sentinel thought to himself.

He then looked up from his march at Serenity, smirking slightly. She didn't return the gaze, but felt him looking at her like a prize and she didn't like it.

This did not go unnoticed by Optimus (or Ultra Magnus). Trying his best to keep his calm, Optimus stepped closer to Serenity in a protective way. 

"You have my word.", Optimus replied. "And we all know what that's worth, don't we?", Sentinel said. 

He finally torn his gaze from Serenity in order to scorn Optimus. "More than yours.", Serenity whispered to herself, thinking no one heard her. 

However, Serenity's words encouraged Optimus. "Come on, boss bot! Why don't you stand up for yourself?" Bulkhead asked.

"Because he knows his place.", Sentinel smirked. "How about I put you in your place?!", Bulkhead yelled out, preparing to attack Sentinel.

Then, others moved in to stop the two from fighting. But, as Serenity was holding Bulkhead back, she was silently cheering for him.

"Stand down! All of you!", Ultra Magnus commanded, as he slammed his hammer into the ground. Everyone then looked at him. 

"These are serious charges and they will be investigated! Optimus Prime, show us where this supposed Decepticon battle took place! Your crew will remain with Jazz till this matter is settled.", Ultra Magnus continued. Serenity then stepped forward. 

"Ultra Magnus, I wish to accompany you to the site. Being there might help with some of my memories.", Serenity said. Sentinel, however, didn't want that. 

"With all due respect, Princess. If this supposed battle took place, Decepticons may still be lurking around.", Sentinal said. Serenity was now done with Sentinel, before turning around to face him. 

"Sentinel Prime, please choose where you stand. First, you are so certain that... What did you call me and my team? Glitch detain flunkies
