The conversation between Martin and Tim that he overhears in the hall is also really funny. The fact that they're talking about how he should probably go to therapy meanwhile Jon is foaming at the mouth and screaming the date of the recording like he can hear the clock ticking
I just started season two of The Magnus Archives today, and I've just got to say Jon's rampant paranoia is so funny to me
Like, he's not even good at hiding his investigations. He goes to his colleagues' houses after work and the very next day they're like "Jon what the fuck" and report him to their boss who is so done with his antics
And also he's so focused on finding out who killed Gertrude Robinson (a valid concern) that he does not even notice Sasha is POSSESSED. The single-minded focus is insane.
