What I found particularly interesting is that Guinan seems to be able to repel Q's powers. When Q raised his hand to "dispose of her", she does the "Yoda thing". For the next minute or so, both adversaries hold their positions while Q explains Guinan's "true" identity... sort of. Also, Q gets pissed off whenever Guinan enters the room. So help me, he kinda... freaks out. I wonder... what this could mean....
