I really want to see a scene of just Halsey and Jul having a normal conversation together. It’s clear from Escalation that he puts a lot of trust in her, defends her from his compatriots even, and she sees right through his act as a religious zealot. In essence, Halsey is the one and only person who Jul can be open and honest with, and I think that’s absolutely fascinating.
Imagine the two of them trying to find some kind of common ground outside of hatred for the UNSC, and they stumble onto the subject of their children. Jul laments how he’s not seen his sons for years, that he cannot even reveal his identity to them, to which Halsey says that he’s lucky enough to know he has children out there who are safe - where she has nothing, since Miranda is dead.
For the first time, Jul finds himself feeling pity and empathy for a human, and he’s kind of okay with that. Maybe some of them aren’t so bad?
