yeah its good to have the badass Don back, although you get the feeling he is just one thing away from breaking down completely. Young Don stuff was pretty cool too, best part of course was him fucking over the asshole Jaguar dealer.
I love Pete's little thing at the end, "you're going to bed tonight and you won't be sure of anything!" haha what a shitty defense, Pete is the best thing to watch whenever he fails at things. But yeah, Trudy wants to keep up appearances so she will let Pete keep on being Pete, just nowhere near her neighbors and kids anymore. It'll be an interesting contrast to Betty to see if Trudy keeps it up for the rest of the series, or if she waits to find a better guy and then divorces - I think right around this time is when divorces became more easy to get in NY, whereas before you had to fly out to Nevada and shit.
