Normally, Derek liked his solitude but tonight he was feeling restless, as if something was tickling the back of his neck and he couldn't scratch it. He felt the link he had to Scott and his pack, still considering himself as part of the Pack with Scott as the Alpha. It was never a job he wanted anyway, so he was happy to let Scott lead even if Derek had evolved to a full Alpha form. Scott was still a natural Alpha and that meant something and Derek had no intention of trying to change the pack hierarchy.
Sighing, he rolled off his bed and to his feet, slipping on his shoes and pulling a t-shirt over his head he left the loft. Maybe a run would settle him down so he could sleep.
A half hour later he found himself standing outside the Stilinski house, staring up at Stiles' window. The Sheriff's car wasn't there, so Derek guessed he was working that night. The light was on in Stiles' room, and Derek was still restless so he jumped to the roof and tapped on the window before opening it and sliding into the room. He could see Stiles' face reflected in the light of his computer.
