Fucked up Celia got off the drugs just to get on the power trip, explaining to the innocent waitress that the cow goes "moo", Andy finally got to play with real doctor (Alanis Morissette, no less. Respect), Shane is proving once again he is ready to try anything (jumping to the deep end, ha?), Silas is irrelevant and boring as usual, but harmless, and Nancy just don't struggle anymore. She stopped swimming and just floating, desperately collecting pieces of her life into some structure, trying to create some sort of a shape out of her life, to make it at least look normal, just to watch it explode and crash few minutes later time after time.
Great season overall, and really great finale. Celia is getting a team that is too good to be true, Andy simply blew it, Shane made it big time, Michael Corleone style, and Nancy is getting into even bigger mess. Can't wait for the next summer.
