05E08 - Lady Lazarus

Megan has been lying to her colleagues, including Don, about her whereabouts at certain times of the day. She is caught in the lie by both Don and Peggy. She is able to make up a credible enough excuse to Don, but Peggy confronts her on it. Based on that discussion, Megan decides to come clean to Don about what she's been doing. Don's reaction surprises her, which leads to a major change at SCDP. But Don's true reaction may actually be closer to what she had anticipated based on an encounter Don has with Peggy. Meanwhile, Pete is still feeling more fulfilled at work as clients, without even having met him, are giving him gifts. But he is feeling more and more restless at home, especially after he learns that his train commuting colleague Howard Dawes has embarked on an affair in the city. Taking a cue from Howard and given the opportunity, Pete embarks on a wannabe affair of his own, the "wannabe" part based on the insecurities of the other party.
