2. Will there be repercussions for Bran?
He has these nifty gifts now and although they are useful, he should probably look this gift horse in the mouth. This is a George R.R. Martin story, after all. Could going into others heads, as Bran did with Hodor, be dangerous? Is there a danger that he could forget who he is and live in others? What if he can't find his way back to himself again?!
