Graham and Arty discuss Jesse (and Katie) in an "", at the head of the episode.
GL: It won't save you, condemning me, and sharing only partial versions of what I did, to make me look bad. That won't save you! I don't know why these people think they're suddenly going to be suddenly forgiven by some of the most psychotic activists in the world because they throw me under the bus. You know? They won't save you. They'll keep on lying about Jesse Singal until the end of time.
AM: It's the hardest thing, because it breaks my heart, because I actually am so upset about what happened to Jesse. And as much as I don't entirely agree with Jesse, I'm sympathetic to him and I always have been. So it really upsets me - I'm so angry with him right now. Literally I asked for, I literally asked a teensy bit of support for Graham, and he's like "nah, can't do that". What a jerk!
(More nuanced discussion follows, but upset Arty's always cute).
