Of fucking course it was Peter.

That stupid asshole decided the best way to get revenge -for some reason or the other- on the pack was to try to make them go through their worst memories again.

With the rest of the pack there in the memories.

Lydia's was resurrecting Peter all over again, being used like that, losing control of herself.

Jackson's was being the Kanima, killing people and forcing his Alpha into the pool with only a weak human to help him.

Isaac's worst memory was being in the freezer, watching his dad terrify Camden into leaving, hurting him.

Às they cycled through the pack's memories, they were shocked by the trauma that some of the pack went through in their 17-18 years of life.

"Stiles, have you gone yet?" Lydia asked, shaking her hair out of her face. Sweat matted the pack's faces as they stared at the human, who shook his head.

"Man, bro, you're lucky!" Scott exclaimed, shaking his head.

Stiles shrugged with a rueful smile.

"Sure, Scotty, sure."

Time and space started to warp around the pack as they went into Stiles' worst memory.

"Where are we?" Derek asked, turning to a pale Stiles.

Stiles' eyes were glued to a light-brown-blond-haired boy leaning on the graffiti-ed street wall.

"Newt?" His voice broke as he stared, his clothes melting into other, darker colors, a gun materializing at his side as the pack stared at the nearly-palpable emotion between them.

"So, what, huh, Tommy?" The boy-Newt, apparently- snarled, black veins nearly bulging. "Did you want a sit-down, huh? A talk about how bloody cheery it was in the Glade?"

"No, Newt," Stiles' voice cracked. "Just-Just come with us, ple-ase" He would never admit to the voice crack.

"Did I ever tell you how I got this limp in my leg, Tommy?" Newt snarled. "I climbed up the wall. I couldn't take it anymore. I jumped."

Lydia gasped, tears swelling up. She blinked them back.

"I'm gonna blast, Thomas!" A voice yelled from the van parked a few feet away.

"Vince, just… Gimme five minutes!" Stiles yelled back.

"Fine! FIVE!"

"Come with us Newt, please," Stiles pleaded with the blond. "You know Min and Bren are coming with the serum soon, please!"

Black goo slowly dripped down from Newt's lips, staining his pale skin.

"If you've ever been my friend, kill me. KILL ME!" Newt's eyes cleared, staring into Stiles' eyes, smiling at what he saw there. "Can't… save… me this time, love."

"I can try!"

"Please, Tommy. Please."

Stiles raised the gun, cocked it with the safety off.

He shot it, tears finally spilling over as he watched his Newt die.

Time and space warped around them one last time, surrounding the astonished pack.

Stiles trembled in front of them.

"Why… Why? Bad enough I had to go through that once, but why?" The anguish in his voice scared some of the pack members.

"Becau-" Peter was cut off when Stiles whipped around.

He pulled a knife out of his sleeve and launched it at Peter, stalking closer.

"If you ever interfere in my life again, I'll make sure there isn't enough of you left on any plane to resurrect again." Stiles whispered, his voice full of hidden power. "I can do that, you know. I have several friends on speed dial to help me with that."

"Now," he said, turning to the rest of the pack. "I'm gonna go and vid-chat a couple of people. Don't. Follow. Me."

He left.

"What the hell just happened?!" Isaac exclaimed.
