It’s been fun seeing so much of Kirk this season, but does that mean he’s now a regular? I don’t see how he could take a position on the Enterprise for years yet, so would that imply he just keeps coincidentally visiting all the time? Starts to strain plausibility after a while.
I’d say Kirk being here for multiple episodes was necessary to resolve La’an’s growth as a person. Whether it needed to be Kirk himself, obviously not, but since they started that thread they had to complete it. I do hope he doesn’t just continue hanging around next season, though. He has a post on the Farragut to attend to.
