Pretty quiet finale to a pretty quiet season. Except for Pete getting his ass kicked on several occasions and Lane's suicide, there weren't any really big moments. The cliffhanger, if you can call it that, is whether Don is going to go back to his dirty ways? Now that he's given Megan a foot in the door to an acting career, it seems to me he's given up control of her, which could lead to him saying "f*** it, I'm going to have some fun." Also, he's obviously feeling guilty about Lane's suicide, in addition to his brother's suicide.
Still one of the best shows on TV. Hopefully they don't take another year and half off.
