ONE SHOT. I've had this in my mind for a while now, so I just decided to finally write it to get it out of my system. Set during S02E02. Stiles comforts Isaac when they try to break him out of jail. Derek gets a hint of jealousy. Then later, Derek finds out that Peter offered Stiles the bite and now he really gets jealous.

Derek breaks up with Stiles in order to keep him safe. Unknown to him, Stiles has a pact with Castiel so that if he ever needs him, then Cas will come to the rescue. Derek has no idea that Stiles even knows Cas or the brothers. Just an idea that popped into my head-no idea where I'm going with this. Sorry for the sucky summary.
