Best: Don and Betty reunited (and it feels so good)
Episode: "The Better Half" (609)
Don and Betty haven't shared much screen time since she left him at the end of Season 3, which made their intimate reunion at Bobby's summer camp all the more surprising. Betty invited Don back to her cabin, and into her bed, and the exes shared some stunningly frank pillow talk (Betty even expressed pity for Megan).
