Well the new season finally begins tonight, another 2 part opener. We last left off with Lane killing himself over being forced to resign by Don after he stole money. SCDP ends up buying up more office space in their building, Don gets Megan a part in a commercial and Peggy has gone over to work for Ted Shaw at a rival agency and Rodger is taking LSD again. Finally, at the end we see Don propositioned by some chick in a bar about how she wants him to get with her friend and we do not see what decision Don made(surprisingly Don hasn't cheated on Megan yet that we know).
Hopefully this new season will turn out as well as the previous ones did, though I will admit I will miss the character of Lane. I will also admit I would not be upset in the slightest if we do not see Betty at all this season.
