JFK is starting his speech about the Cuban Missile Crisis as Don watches in concern. He picks up the phone to make a call, but thinks better of it and simply listens...

...and then he's arriving at SC the next morning as JFK's speech continues on the audio. Joan happily greets him, which is a really nice moment, and when he smilingly asks how she is, she confesses she's "like everyone else today. Very distracted." Peggy emerges from her office (still calling him by his given name, by the way; I'm glad she made that stick) and asking how California was. He looks at her office (she's got a pink door instead of the standard blue; baby steps) and asks if he works for her now. Hey, it's getting closer to the truth. Peggy smiles and explains that Roger gave her permission, and that she landed the Popsicle account. Don turns back to Joan: "Other than her office and haircut, is there anything new I need to know about?" Heh, but how awesome is it that Don actually noticed exactly what was different about Peggy's appearance? Joan's like, honey, please, and follows him into his office...
