I hope this downward spiral of Don's comes to a head at some point - it's getting boring to watch. He needs to hit rock bottom and either have it smash his work veneer, or allow it to help him rise from the ashes. One would hope that going on a 2-day bender and waking up with someone he doesn't even remember MIGHT make an impression on him that he needs to snap out of it. We'll see.
I was left wondering in the flashback if we're meant to think Roger never actually offered him a job, and that Don simply fudged it and hoped Roger would think he just forgot due to the drinks.
Loved the scene between Lane and Pete. He summed up Roger perfectly a "useless child". Lane is becoming a good mentor for Pete.
In the scene with Ken Cosgrove, I almost thought they were going to have Pete fall ass over tea kettle in his chair when he was leaning back in satisfaction from his talk with Ken.
I kind of liked the Peggy/Rizzo moments. She called him on his B.S. I wasn't at all surprised that she went as far as she did because she has shown time and again that she'll do whatever she has to in order to get the job done.
