Two of a Kind

Coffee

Derek walked up the stairs with Erica in tow rambling about her physics teacher being unfair for the amount of homework he hands out. He paused when he reached the top and saw at the end of the hall Stiles and Theo.

Erica paused as well even cutting of mid-sentence when Theo leaned in and kissed Stiles.

"Stiles seems to have changed his tune," Erica smirked.

Derek frowned. He was surprised to see Stiles so receptive to Theo. In fact, Stiles looked almost smitten.

When Theo pulled away, only then did Derek continue walking.

Theo walked by them with a large grin on his face.

"Oooh, he seems thrilled. How'd the date go?" Erica asked once they approached Stiles.

His cheeks flushed heavily once he realized Erica and Derek had seen the kiss.

"It went really well actually," Stiles dropped his eyes to his feet.

Stiles pushed the dorm room door open hoping that Erica wouldn't pry. He didn't get so lucky.

"So, are you gonna see him again?"

"Uh, sort of," Stiles shrugged. He noted the shower was running letting him know Spencer was home.

"Sort of?" Derek raised a brow.

"He's gonna meet me at Kai's party Friday," Stiles shrugged.

"You're gonna let him meet Kai?" Derek didn't know why that surprised him.

"I thought you weren't interested in Theo?" Erica frowned.

"I wasn't, but at dinner I realized he was different than I thought," Stiles shrugged again.

"Stiles, hey how'd dinner go?" Spencer asked eagerly as he stepped out of the bathroom.

"Fine," Stiles spoke avoiding his brother's gaze.

"Just fine?" Spencer frowned, he obviously didn't like the sound of that.

"I'd say it went better than fine, you like him," Erica teased poking Stiles' cheek playfully.

Stiles laughed, swatting her hand away.

"Do you?" Spencer asked excitedly.

"He's different than I thought, I'm warming up to the idea, but I'm not sold yet," Stiles waved a dismissive hand.

"That's more than you're giving Kai," Spencer snorted.

Stiles bit down on his bottom lip but didn't respond.

Derek caught it though, something about that made Stiles nervous. Did Stiles like Kai too? The idea didn't sit well with Derek and he didn't like that. He was getting to invested in the twins. He needed to stay out of it before he got himself hurt.

"You okay, Der?" Spencer asked looking at Derek with concerned eyes.

It was then Derek realized he was glaring down at his shoes.

"I'm fine," Derek answered, wiping the glare from his face.

"Der?" Erica asked in surprise, "No one ever calls you that,"

Derek felt the accusing eyes of his best friend on him as he tried to shrug it off. She was trying to point out that Derek never LET anyone call him that. It was reserved for those closest to him.

"He asked if it was okay," Derek shrugged. He actually kind of liked that Spencer called him that.

Erica smirked, but thankfully didn't say anything more about it. Derek knew he'd be hearing about this later.
