I could see a break up occurring instigated by Tommy. Tommy may worry that he's holding Buck back from exploring who he is. Buck just came out as bi and Tommy's the only man he's been with. Buck could be wanting a relationship but Tommy's worried he'll have regrets trying himself down to the first man he's been with.
So they break up for an episode or two.. Buck goes out with other guys, maybe goes back to women but he's still into Tommy
And then Tommy's helicopter crashes in the mountains and Buck goes searching for his man!! That part is just for me 😂😂😂
