[Dean doesn't blink, and doesn't look away when Stiles starts talking. He's watching now, watching for lies, watching for truth, watching for anything at all that he can use before it can be used against him. He was never manipulative, he isn't now, but he's the weakest thing on the planet now. He learned that he only gets one chance to notice the detail that will keep him out from under the knife, that vigilance could prevent him taking an infected person back into camp before they started showing the major symptoms.

Stiles is telling the truth, but knowing that doesn't explain why. Knowing that doesn't make it any less difficult to believe there isn't something here he's missing.]
