Toby had a complete breakdown, and was taking pills at one point for it.
He’d also be ranting to this girl at the workout, probably relieving some steam about his frustration which seems like a dick move except… they’ve never really shown who else Toby would talk to. Kate has her brothers, mom and that one girl from the eating group. Toby has her brothers too, but he can’t really complain to Kevin and Randall too that level about Kate..
Kate about to have an affair might be complete out of character, but we’re also still working through her early adult relationship thing which I think might be a trigger for her self-esteem body issues that could tie into this somehow.
I might be an episode behind too. Only one though.
