That's a good synopsis Melissa, thank you for that.
There have been some fierce discussions in past Mad Men threads about the behavior of some the characters, especially Don and Betty. I can't blame anyone for being infuriated at Don for all the things he's done over the years, but the only time I've ever been infuriated at him was when he fired Salvatore for rejecting the advance of Lee Garner Jr. who then insisted Salvatore be fired or else they were going to lose the account.
He fired Salvatore, then they lost the account anyways. I don't think you should ever desert a member of your team that way, but Don does have a history of being a deserter. In the case of Sal, Don sold out for nothing. Captain Picard would have stuck by Sal even if it meant bankrupting the agency.
I hope they bring back Sal one day. They did bring Freddy Rumsen back after all.
I wonder if Glenn will come back. It wouldn't surprise me if he didn't since Matt Weiner has a history of keeping the flings of the major characters brief, like most of Don's mistresses and Father Gill (after his attempted courtship of Peggy). I think Don's original mistress Midge might continue to make cameos until the series is over, especially with the hippy era approaching. Maybe she will meet Sally?
