Casting buff spells or even healing spells is CLEARLY prep for combat (why heal if there will be no combat?). Fascinate should have been gone as soon as the first spell was cast, and the villain should have a full-round action at that time.
Ditto for moving into flanking positions. Not all combat is attacking... maneuvering is an important combat action. I'd make him do a Spot check to notice each such move, though, because a reasonably stealthy approach should still work.
In certain limited cases, the BBEG may even have reason to think that PC's that study or look at him hard are really assassins studying for a Death Attack, and regard such looks as combative behavior! I'd save that excuse for an unhinged paranoid type.
