I don't think Bryan is going to kiss / cheat on Miller.. I feel like Riley was probably really close to Bryan when they were on Farm Station together (and close to Clarke when they were on the station together?) But if Riley is gay, I feel like if Bryan felt some kind of deeper connection to him, they probably would have already explored that previously, and perhaps a Briller break up will come up because Nathan finds out.
I wasn’t saying that Bryan would cheat on Miller. Absolutely not I don’t see that. I was trying to think of reasons for Riley’s existence (it could’ve easily been Monty who recognised him, not Bryan, and I wouldn’t be having this thought - everything happens on screen for a reason), and I thought maybe because Bryan was the one who recognised him first, they might have something going on further in the season (if he lives) (dear God, I hope he lives).
And yeah, I think they were definitely good friends (and yes, apparently Riley was with Clarke, too) so maybe you’re right - if there was going to be a connection they might’ve already looked at it. But I don’t think they would’ve.
Miller and Bryan have a long standing relationship, the only one on the show. They canonically share a room, showing that they’re seen as a legitimate enough relationship to do so. That means they love each other, they’re important to each other, they were in it for the long haul. If Bryan and Riley ever had that relationship, I highly doubt Bryan wouldn’t have already told Miller about it.
So my guess would be that Riley might’ve had an unrequited crush going on, and after the break up (because we’re assuming there’s going to be one no matter how much I’m crying over that) he gives it a shot with Bryan, who turns him down. Riley’s gonna have more than that going on in the show obviously (both because Bryan’s a minor character and not important enough to introduce someone new for, and because Clarke knew Riley from before), but if that’s what’s happening with his relationship with Bryan, then I think that’s interesting.
It would also be a good moment for Bryan to realise, inevitably, you know what, Nate’s the one. I can’t let him go. I’ve got to get him back and then they’ll be together for the end of the world and all that.
Hopefully, with an actual moment to explain myself, that makes more sense.
