Teen Wolf or more importantly Stiles and Derek

[certainthings]

Where does this gif come from? Is there a video? Are there decent quality pictures? Because I sincerely really and truly need to make me an icon of Tyler biting Dylan. It makes my pants the happiest.



Also. Which eps have the most amount of Derek/Stiles scenes? I really want to make some icons but all the episodes sort of just bleed together for me and well ... HELP. Please?
