What was almost too awesome to behold, like looking into the sun, was Betty calmly taking a drag from her menthol and then telling Don exactly who he is, with no pretenses and no agenda; just laying it all out because she’s known him well, known him long, and known him intimately. That combination puts her in a very distinct position in Don’s bed. “That poor girl,” she says sadly, of Megan, “She doesn’t know that loving you is the worst way to get to you.” There’s nothing bitchy in that line; no attempt to hurt any of the people she’s talking about. That’s incredibly rare for Betty, which should give you some idea of how much she’s grown up lately.
