"Where's Stiles?" Derek asked as Scott walked into the loft. The other alpha shook his head, walking over to Lydia. Feeling his phone vibrate in his pocket, Derek checked it to find a message from Stiles.
-hey. i don't think I'll be able to make it to the party. Something came up. Come over later?
Derek frowned, wanting to ask what'd happened; Stiles had been raving about how drunk he was going to get, only that afternoon. He sighed and typed his reply.
-Party ends at nine.
Derek put his phone onto the coffee table and walked towards Scott, who had been talking to Isaac until Derek's eyes burned red at his beta. Scott turned to look at Derek as Isaac walked away.
"What happened?" Derek asked.
Scott's brow furrowed, "It's a personal subject for Stiles. And I mean very. I'm sure he'll tell you about it later."
