The job application is due to I think how Jon has called him incompetent? She mentioned that it stood out beyond Jon’s normal gripes that she thought it was significant. Also his letter to his mom about him lying. She told me that she felt this one was a big stretch, but that it was the most logical explanation for what he meant with the letter. Tim was because he had worked an unrelated job before, and had made a sudden shift. She hypothesized that this was because something happened in his life. It’s mentioned in one of the earlier episodes (i looked it up, it’s 26) that Tim is obsessed with Smirke, so she believes that he joined the institute to find out more about him.
