Stiles ripped open the Shower curtain to see Liam laying down in the bathtub wrapped up in duck tape making Stiles look down and sigh while Liam let out a few muffled yells as Stiles slowly closed the curtains again. The two of them walked out into Scott's room before Stiles and Scott sat at the foot of Scott's bed.

"So, you bit him?" Stiles asked and Scott nodded. 

"Yeah..."

"And you kidnapped him?" Stiles asked and the answer was the same.

"Yeah..."

"And brought him here?" Stiles asked. and Scott looked at him.

"I panicked!" He said making Stiles nod.

"Yup...This isn't going to end with us burying the pieces of his body out in the desert, is it?" Stiles asked and his only response was Liam's muffled screams. "As a reminder, this is why I always come up with the plans! Your plans suck!" Stiles said.

"I know-which is why I called you. So, what do we do?" Scott asked.

They both said at the ground before Stiles looked up and at Scott. "I'll call Ava."

🔥🔥

Ripping the shower curtain open Ava looked down at Liam wrapped up in duct tape before closing the curtain. "So while Lydia and I were in Sean's house, he was at the hospital pushing Liam off the roof and you bit him to save him?" Ava asked and both boys nodded. "Instead of being civil you what knocked him out and duct-taped him and put him in the bathtub?" She asked and again both boys nodded. "Well, the chances of surviving the bit is incredibly high. Let's be civil and talk to him." Neither boy moved. "Now! Get him out the tub!" She said making them shoot up and run to the bathroom. They came back with Liam still in duct tape but sitting on a chair this time.

"Liam, we're going to take the tape off your mouth. If you scream, it goes right back on. If you talk quietly, it stays off. Got it?" Stiles asked and Liam nodded. Stiles was about to rip off the duct tape when Ava hit him around the head and then took off the tape gently. "Okay, Liam...Now, you've seen a lot of confusing things tonight. And more confusing things are going to happen because of the confusing things that happened tonight. Do you understand?"

"Not really..."

"I didn't understand either..." Scott mumbled making Ava and Stiles turn to him.

"Maybe you should tell him," Stiles said.

"Tell me, what?" Liam asked and Scott sighed.

"Liam...What happened to you...What I did to you...Which I had to do to save you? It's going to change you..."

"Unless it kills you" Stiles added making Ava shoot a dirty look at him while Liam started to cry. "Shouldn't have said that."

"His chances of surviving are fifty to a hundred, unlike yours which were zero to none," Ava said. Liam started to cry. Ava crouched down in front of him.

"Liam, you are going to be completely fine, you are not going to die." Ava said softly.

"Probably not..." Stiles said making Ava stand up and smack Stiles in the shoulder. "Okay, possibly not," Stiles said rubbing his head.

"Untie him, idiots," Ava said and they took off all the tape.

"Liam are you okay?" Scott asked while Liam slowly stood up as Ava slowly moved out of the room as she fully intended to let Liam leave and not deal with stupidity anymore. Liam found Ava getting ready to leave by the front door.

"You should leave now if you want to leave." She said walking out the door leaving Liam to wonder why she helped him escape.

Ava, Kira and Lydia were in Science class when they were going over Lydia's math notes which were codes. "These are your math notes?" Kira asked. "No wonder Malia's failing."

"Um, some of them are my notes," Lydia admitted as more coded appeared on her laptop. "The rest I think might be a code."

"But you don't remember writing it?" Ava asked.

"Not in the slightest. But considering my drawing of a tree led us to the Nemeton, I should probably figure out what it means before it tries to kill us." 

"I remember that," Ava said smiling. 

"Maybe it's like the Enigma Code like Allies used. My dad was a World War II buff? And my mom was, well, in it." Kira suggested.

"I think it more like the Vigenere Cipher," Ava suggested. 

"Do you know how to crack it?" Kira asked Lydia.

"With a key." She answered. A set of the actual key was dangled in front of Lydia by her mum.

"Remember the rules. No more than six people are allowed in the lake house. " Her mum reminded Lydia. "Stay out of the wine." She whispered. "And if anything gets broken, it's getting added to your credit card debt."

"Fine."

"And lock up the basement. From the stretch marks, I found on the walls, it looked like a pack of wild animals got down there." When her mum left, Lydia automatically looked to Ava, who was whistling suddenly finding the ceiling more interesting.

🔥🔥

"We're not sharing our basement." Ava and Malia said at the same time as they all stood in between two buses.

"It's my basement, and my mum noticed how you two tore it up last time." Lydia said.

"Alright, they're still learning," Stiles said. defending his girlfriend and her sister.

"But we're going to use the boathouse for Liam. It's got support beams. We can chain him to one of them." Scott said making them all look to him. 

"But how do we get him out to the lake house if he doesn't trust us?" Ava asked.

"I say, if it keeps him from ordering someone, we chloroform the little bastard and throw him in the lake," Stiles said while doing hand gestures.

"We're in!" Malia and Ava said at the same time, raising their hands making them all roll their eyes.

"Ah! I hate it when you do that!" Stiles cringed.

"We're not killing or kidnapping him!" Scott said as Ava shoot Scott a dirty look.

"Didn't you already try kidnapping him?" Ava said.

"Then let's be smarter. We tell him there's a party and invite him." Lydia said making Stile raise his eyebrows at her.

"So, are you going to ask out a freshman?" He asked and Lydia shook her head.

"No...I'm done with teenage boys. But if we're playing a trick on someone...why not used use the trickster?" She said and they all turned to look at Kira who looked at them with wide eyes.

"Who, me? No way. Not me." Kira said, glancing at all of them.

"Yes, you! Do you know what they call a female fox? A vixen!" Lydia said as Malia looked Kira up and down and Kira just looked at her with wide eyes.

"Me?" Kira said awkwardly and Lydia smirked and nodded.

"You can do it, Kira. Be a vixen!" She said and Kira made a face and sighed.

"I still don't get how this guy has no mouth...How does he eat?" Stilinski said look at the wrist keyboard thing Derek brought while Ava was breathing heavily with her eyes closed.

"Peter didn't get a chance to ask...he was fighting off with a tomahawk buried in his chest, so..." Derek said sarcastically making Ava chuckle.

"You, okay? With the full moon?" Derek asked.

"Yeah, I have way more control than Mal, but lately I have to need to use Satomi's mantra," Ava said.

"Who runs around with a tomahawk?" Stilinski asked getting back to the topic.

"I carried one of I.E.D removal in Afghanistan. It's military." Jordan said coming up to Ava. "So is that."

"Do you know what it is used for?" Derek asked as he looked at it.

"Well, this one looks like it's been modified." He said looking up.

Stilinski looked over at Derek and Ava who nodded. He nodded to Ava, who walked over to the door and shut it. "Show us."

"Okay, I think I got an IP address." Jordan said making Stilinski and Ava step forward-leaning her hand on the desk to look over his shoulder.

"That means we can find him, right?" Stilinski asked as Ava moved from the desk, facing the wall, breathing getting heavier. Her eyes started to glow, fangs and claws growing.

"What three things cannot long be hidden. The sun, the moon, the truth." Ava muttered. Stilinski noticed Ava and nudged Derek with his shoulder. Derek walked over to Ava.

"You okay?" Derek asked.

"Yeah!" Ava said opening her eyes, still glowing. "I thought I was good with full moons. But lately, I've been losing control more."

The glove started making a noise bringing the Hale and the unknown Hale back to the reason they were here. "What was that?" Derek asked moving back to the desk.

"I think I found a message. Does anyone recognise the handle Benefactor?" Jordan asked making them look at the laptop.

"'Money transferred'. What does that mean?" Derek asked making Ava sigh.

"He's an assassin."

🔥🔥

"You know, just because this guy connected to the school's Wi-Fi doesn't mean he's still here," Derek said watching Stilinski as he held out a gun, walking through the high school.

"True. But, I've seen enough in this school to keep my gun in hand when walking in after dark." Stilinski said. "Like blood," Stilinski said pointing to a puddle of blood on the floor underneath a door making Derek and Ava look at each other.

"That doesn't make sense..." Derek muttered.

"Yeah, no kidding."

"That's not what I mean...I should have caught the scent before we walked in." Derek said making Stilinski glance at him before looking around. Derek walked over to the door and went to open it but Ava and Stilinski stopped him.

"Hold on. You nervous makes me nervous." Stilinski whispered.

"I heard something ticking," Ava whispered. He shined the torch into the window of the door then slowly opened the door but stopped seeing a wire connected to the knob. 

"It's an explosive- a claymore. That was what the ticking was." Ava said. The two looked at Ava with raised eyebrows. "What I read." She stood up.

"Get down!" Derek yelled before grabbing Stilinski and Ava before a tomahawk could hit them. Ava took a deep breath before growing her claws and running over to the mute. She swung her claws at him before kicking him.

He swung another tomahawk at her making her duck while Derek grabbed his arm, knocking the tomahawk out as he twisted the Mute's arm around his back, kneeing him in the stomach before grabbing his other arm, holding them both behind his back. Stilinski stood up, pointing his gun at the mute. "You have the right to remain silent. Anything you say can and will be used against you in the court of law. You have the right to an attorney. If you cannot afford one-" Stilinski said, starting to put cuffs on when Derek noticed Peter running over.

"No! Peter, No!" Derek yelled, Ava, grabbing Stilinski, pulling him to the side as Peter jumped the Mute. He slashed his claws over and over blood splattered across his face. Ava, Derek and Stilinski slowly stood up looking at Peter in shock as Stilinski pointed a gun at Peter while he wiped the blood off his hands.

"We've learned a better way," Derek called out as Peter walked away.

"I'm a creature of habit," Peter said.
