I think this is like the third time where Ian flipped flopped between tj and Jo. Like Ian doesn’t owe them loyalty but it’s more of just bad writing imo. They aren’t communicating anything between tj and Ian, I’m pretty sure they just fuck every time they see each other. And after seeing it for the 3rd time it’s annoying, at least Ian and Jo can talk their feelings out for a second. And that’s also why it’s obvious that Ian will end up with Jo, so we’re just wasting time.
