Stiles fever had broken just as the sun had been setting but the human had slept. There was no pain to wake him and his abused body needed the extra rest. Plus Stiles actually felt safe, something he hadn't felt since the capture.
When he felt Derek's grip on his arm tightening, the nails digging into his fragile skin, Stiles made a soft noise of protest and started to slowly wake up.
He turned his head and opened his eyes only to see Derek looking pissed off and it looked like he was pissed off at him. "...what did I do now?" Stiles asked, his voice croaking from sleep and how dry it was.
