#I don't really take the scene in ep162 to mean that they were never friends Tim's just upset for Sasha and Sasha resents not being promote

[i-will-change-this-someday]

I was talking with my brother about this a while ago, and I was telling him that, to me, the reason Tim reacted so strongly to Jon stalking him is because it was probably a really big betrayal and trigger for Tim.

It's implied, at least to me, that Jon and Tim were decent friends; Jon wanted Tim to join him in the archives, Jon trusted Tim not to pull a prank on him, Tim tried to calm Jon down when he was obviously stressed, and Jon even admitted to Tim that he wasn't doing well, (and coming from Jon, I take that to mean they were on pretty good terms.) Tim was helping Jon limp around in the tunnels, and didn't leave him when they got attacked, Tim happily threw Jon a birthday party.

So when Jon falls into a supernaturally induced paranoia spiral and starts looking at everyone like they're going to kill him, it's pretty bad for their relationship, and then Jon is stalking Tim's home and that's even worse for their relationship.

Tim explicitly says that he just wanted someone to support him after his traumatic experience, but Sasha is acting odd, and he's not as close to Martin, and when he turns to Jon, Jon is looking at him like he's a murderer.

And it is, again, at least to me, implied that Tim was a suspect in killing his brother. He was the last human to see Danny alive, and if questioned what happened to him, all Tim would be able to tell them was something that should be impossible. (In Ep 79 Tim wants to record what's happening because he wants evidence, and if I'm reading it right, they think Jon might try to kill himself, so Tim doesn't want to be suspected for the death of another person he cares about.)
