I’m probably looking too deep into this scene but Franks call with Kendal prior to the meeting with Josh had me thinking he’s looking for any chance he can get to back Kendall. It’s when I heard Frank tell him he can show Josh who he really is if his dad “has to step away.” Seeing that subtle reaction from Logan made me think there’s no way he wanted Frank to say something like that lol. I think he’s playing the part for Logan so he doesn’t get in any hot water but still very much supports Kendall and wants to see him on top. I think he’s gonna end up switching. I guess the same could be said for several other characters about switching sides but I think Frank is inevitably going to Kendall even after he almost assasinated his dad in the sun.
