The season two finale tied the entire season together, and topped it off with a nice little bow. I couldn't have asked for anything more. Except maybe a more slow, painful death for Lila. She deserved far worse than how Dexter got rid of her. He showed her mercy, at least, Dexter's form of mercy. Or maybe it was his way of saying thank you to her for killing Doakes when he couldn't do it. She did clean up his mess. But I didn't like her from the beginning, and what she was doing to Angel was wrong. And then trying to kill Rita's kids and Dexter, she deserved worse. The 'Greetings from Miami' postcard was awesome. I would like to know how he disposed of her, though.
And the hint that he's going to try new things next season has me super excited. I can't wait. YAY for Dexter! :)
