Another healthy sign is just how happy Don seems. There is a rough patch in "A Little Kiss," but overall, he seems much more at peace than at any other time during the series. This can surely be credited to Megan, and thus, her presence is welcome. Their nuptials do seem a little fast, but she's proving to be a good match who can inspire Don to be his best self. Better still, he already told her his secrets between seasons, including that he is really Dick Whitman, so there is no dark cloud hanging over them.
Pete's marriage to Trudy (Alison Brie) in Mad Men, on the other hand, seems far less suitable. Pete is clearly unhappy no longer living in the city as of "A Little Kiss." He doesn't exactly cheer the advice of his buddy on the train, who suggests that Pete stay at work later, if he comes home at all, but it does appear that Peter considers the words. How long before Pete begins to act on them? And how long after that before Trudy leaves him?
Roger, too, isn't happy in his marriage. He ignores his wife, Jane (Peyton List), or tells her to shut up. It's not like Roger has ever been happy with anyone (except for Joan), but this is the bed that he made. If he doesn't want to stay married, then get a divorce. Having an unhappy home is not doing him any favors, and with everything else going on, Roger needs some sanctuary where he can feel at ease. At present, Roger is lacking that.
Pete's relationship with Roger is even more tenuous in "A Little Kiss." Pete wants to push Roger out, and makes a play for his office. Roger holds him off, for now, by bribing Harry (Rich Sommer) to switch with Pete instead. Not exactly what Pete wants, since the office isn't really the issue. But this struggle is far from over. And might Pete just be lashing out at Roger because he is unhappy at home?
The thing is, while Pete is right about Roger not bringing in a lot of new business, or really, any, Roger does have value. Clients love him. Potential clients love him. Roger has great people skills, and is fantastic at entertaining with alcohol and fun. This can be very important for a firm that needs all the business it can get, and is still growing. Not giving Roger his own secretary may make sense, but trying to oust him does not.
