Mad Men is recasting Bobby Draper yet again, this time because young Jared Gilmore is heading to ABC’s upcoming fairy-tale drama Once Upon a Time. But he had some amazing advice for whatever precocious little dude takes over the role as Don and Betty’s oft-ignored son: “Be careful around January [Jones],” he told TV Guide. “She’s not as approachable as the others. She’s really serious about what she does. Everyone else is so nice.” From the mouths of babes, etc. Heed those words, upcoming fourth Bobby! And get in good with Kiernan Shipka. [TV Guide]
