Two of a Kind

Stiles didn't do that

Derek stalked down the hall towards Kai's room. He spotted the guy standing off to the side in the hallway. He was alone with a drink in hand.

Kai looked up to see Derek storming towards him with a murderous look.

Kai had seen that look only once before on Derek and that had been when Kai mentioned Derek's older sister being 'snack material'. Kai quickly set his drink on a cooler that was close by.

"Derek, whoa, hey," Kai put his hands up in a surrendered state.

Derek grabbed the front of Kai's jacket and slammed him back against the wall, "What the hell is wrong with you?" Derek growled.

"I didn't mean to upset him, I just wanted him to know that I didn't usually go for guys like him," Kai responded quickly.

"Why would you tell someone that?" Derek demanded.

"It was supposed to be flattering," Kai tried to shrug but Derek had him pinned so tightly it made it nearly impossible.

"Flattering? You told him, his brother was your type. That's not flattering, it's insulting." Derek was pissed and while all of his anger might not have been caused by Kai, Derek didn't have any problem taking it out on the guy.

"Look, I'm not good with dating. I'm usually the hooking up type, you know that." Kai spoke defensively.

"Is that supposed to make this better?" Derek growled.

"I was trying to tell him I wasn't interested in just hitting it and quitting it. If I was, I'd have gone after Spencer." Kai attempted to shrug again.

"Jackson forbid it, remember?" Derek snapped, his fingers still gripping the front of Kai's jacket.

"So? What Jackson doesn't know won't hurt him," Kai scoffed.

Derek released Kai with a disgust, "You're unbelievable."

"Look, can I just talk to him please?" Kai sighed.

"It's too late for that," Derek shook his head.

"I'll let him tell me that," Kai snapped pushing past Derek.

Derek grabbed Kai's jacket hood and yanked him back sending Kai stumbling into the wall. Derek crowded close once again, "Stay away from him." His tone was threatening.

"Why do you care so much? You barely know the guy," Kai sneered at his ex-roommate.

"He and I have gotten to be pretty good friends actually."

"Then you can tell him that it was a misunderstanding," Kai practically demanded.

"It doesn't matter what I say, you already guaranteed his relationship with Theo," Derek smirked. He knew that would piss of Kai and while it hurt Derek, pissing off Kai was worth it.

"Bullshit, he asked me to crash his date with Theo, so he'd leave him alone," Kai had a cocky grin on his face, thinking he'd caught Derek in his lie.

"I know, and he regretted it. Theo was in the lead anyway, but Stiles felt bad. Well guess what, he doesn't anymore."

"Derek, come on," Spencer pulled Derek back and away from Kai.

"Stiles, please-"

"Wrong brother," Spencer snapped, shooting a glare at Kai.

"Spencer, just let me apologize," Kai sighed defeatedly.

"Did Jackson put you up to this?" Spencer asked then, catching Kai off guard.

"What?"

"Did Jackson put you up to this?" Spencer repeated.

"No, why would he-"
