In this week's Mad Men, Joan stands up for herself, Chevy finally signs off on the firm's work and Don makes it through a full week without cheating on his wife. But an air of ominous dread, highlighted by the riots at the 1968 Democratic National Convention, falls into every scene.

Don and Roger headed to California with Harry and Ted's planning to "kiss the ring" at Chevy HQ in Detroit, but not before the partners met to discuss a very important problem: The merged firm still doesn't have a name. On their way to the Golden State, Roger tells Don - who's doing research - to lighten up and enjoy the fact that their status as big New York ad men means they'll instantly charm Carnation and the other companies on their list. "Be slick. Be glib. Be you," Sterling advises his colleague. "Our biggest challenge is not to get syphilis."

At the hotel, Don turns down Roger's invitation to check out the Strip and instead talks on the phone with Megan, who's upset by the Chicago police's use of force on protesters outside the convention. He jokes about it but stops when he realizes she's about to cry. Because she's Canadian, "You can't even vote," he teases her. "But I still live here," she points out. The cute, attentive way Don's talking to Megan, it's like he actually misses her - could it be that his promise to be a better husband is actually taking effect?

 The next day, Don, Roger and Harry sip Instant Breakfast at an uncomfortable meeting with Carnation and then head to a party with Harry. At the party, Don goes looking for the bathroom but finds a hookah full of hash, which he shares with a room full of new friends. After the smoke clears, he cozies up to a chilled-out blonde and is taken aback when Megan - clad in flower-child garb - shows up. "I quit my job. I couldn't bear to be apart," she tells him, and of course she's a drug-induced hallucination. Interesting, though, that she tells him she has "another surprise" and pats her belly, which seems to make Don really happy. "What do you think it is?" he asks as she leads him through the house by the hand. "A second chance," she replies.

But soon, Megan's replaced by PFC Dinkins, the drunken soldier for whom Don stood up in Hawaii. Dinkins is missing an arm and is - as he informs a confused Mr. Draper - dead. Shouldn't he be whole if he's deceased, Don asks? Dinkins replies "Dying doesn't make you whole. You should see what you look like." And then Don is seeing himself, floating face down in the party house's in-ground pool... and then he's waking up and coughing up water as Roger - who's clearly jumped in to save his pal - is telling everyone to step back and leave them alone.

 Back at the office, after a political argument with Ginsberg, Jim Cutler is agitating for a Cutler Gleason Chaough takeover. With Don and Roger away, "Just lock the gates and leave Pete Campbell as the doorman," Jim advises. Joan's makeup-hawking pal from a few episodes back sets her up with the head of marketing at Avon, but their meal doesn't go exactly as the redhead plans. Perhaps recalling her friend's advice to take control of her career, Joan shows up at the client-courting meal the next day wearing a blue power suit and an air of determination. Peggy quickly surmises that she squeezed Pete out of the meeting, but there's no time to argue because Avon guy arrives. Joan works the interaction, charming the dude and directing the flow of conversation; once they're back at the office, Peggy lets her know that stepping outside the chain of command was unprofessional and will not be viewed kindly by the rest of the firm. Peggy is mad because she had to work for her position - without Joan's support, for the most part. Joan is mad because she's just as smart and savvy as anyone else in the building, but everyone thinks she's a seductress.

Although they're prickly with each other, Peggy still comes to Joan's rescue while Pete is barking at her with disrespect. Upon Roger and Don's return, Cutler, Chaough and Cooper propose a new name for the agency: Sterling Cooper & Partners. "It's the only thing that's offensive to all," Jim says. They all shake on it, but Pete is so upset about Joan squeezing him out of the Avon meeting that he stalks into creative, literally steals the join out of Stan's mouth and tokes up to the strains of Janis Joplin's "Piece of My Heart."
