Okay, so if you've suddenly (*finally*, oy) had the realization that trusted guy in a position of power just might be the archvillain, do you a) rush off to inform the love of your life, who lost her husband in an attempted assassination to stop her from doing the very work she has started doing again right now , or b) sit down and have tea and cookies and have a leisurely discussion of whether or not it could be him? Okay, maybe she is in the Safest Place On Earth (tm) but come *on*, everybody knows that every minute you know who the bad guy is but your teammates don't is a minute asking for trouble. Do they perhaps have *phones* in this universe? Well, no, but there's the Floo network... yes, fiction depends on smart people doing dumb things, but come on, Snape has suddenly gone careless about mortal danger? In three letters, O. O. C.
