I could see a rival agency being set up with Duck, Peggy, (Pete?) and Joan. I think there's a lot of deliciousness that could sprout from there.
Except for the fact that I hate Duck (he ditched his dog!) I would be rooting for that agency.
Lots of refs, and foreshadowing to the war stuff, too.
Really nice moment between Peggy and Joan. I was so glad Peggy had the stones to acknowledge how much Joan had done for her.
Nice moment between Joan & Don at the hospital, too. And the timing was perfect, with the Brits walking in all somber faced just when they were collapsing in inappropriate giggles.
The limb loss was a bit rough (and startled the heck out of my SO who was watching with me for pretty much the first time, resulting in him demanding I fill him in on all sorts of backstory). Particularly because I just got word an acquaintance of ours in Nashville, aspiring singer/songwriter, just rolled her SUV and has already lost her little finger and may lose her index finger on her left hand. So dismemberment particularly forefront on the mind, and then, whammo!
I do think things look bleak for Joan for a while, though. There's no way asshole doctor doesn't take out his frustrations on her.
Oh, and what is happening with Roger? Was it really an oversight that he wasn't on the list. Doubt it. But where they drew him in was under someone and over no one. He's just adrift.
