I've not read the other comments yet, but I will. I will also introduce myself whereever I see that intros are usually done. Suffice to say I'm a Canadian enjoying the Americans since the first episode was aired.

This last episode floored me in so many ways.
My reaction just now, after watching it for the first time? "wow. that was one of the most beautiful episodes of any TV ever."

Most striking line? "everything can be traded, yes?"
Next most striking line? "it's not you, it's me" tied with "you're a monster".

OK, wow. I don't smoke but I feel like I need one. Well, not really. It's quite the intensity, though.
