"Q Who?" - even though I wasn't a big fan of the early eps, this one gives me the *******, when Picard and Guinan are talking, after they've been tossed back to the Alpha Quadrant:
GUINAN: Q set a series of events into motion, bringing contact with the Borg much sooner than it should have come. Now, perhaps when you're ready, it might be possible to establish a relationship with them. But for now, for right now, you're just raw material to them. Since they are aware of your existence .
