Yes, that was a powerful moment when Jon said that when he looks past the shtick, he sees Biden as someone "who knows what loss is," and "knows grief," and Stephen both times said "That's it," and how deep grief "humbles you." I like that they're such good friends that they'll talk about this on the show.
It was fun seeing Jon's kids' names on the blackboard behind him.
I noticed in this episode and the Bolton one that it was very jarring to see Stephen's "we have to go to a break" segments, which were obviously done later (he didn't interrupt the interviews to actually go to a break). Especially because they were so jaunty in the Jon episode, compared to the discussions that they were breaking up.
