I agree this is a great episode/premier. Even though it seems everyone is learning their characters and getting familiar with the show, the characters still seem to be very much the logical origin of what we see them all become later in the series.
Said another way -- while it seems the actors were just getting used to their characters, it also seems they had a really good idea of who their characters were. It seems they just got better from day 1 until WYLB.
I *really* like watching this episode right after the last few episodes of the series because I'm amazed at how far all the characters have come by the end.
