What? Why? Because he's (probably) bi now?
No, I'm not expecting that he's getting a personality change because he's (possibly) bisexual.
But I doubt I'm going to romance Kaidan with my male Shepard if he acts the same way as he did on Horizon.
You know that ME1 features (unofficial?) mShep s/s romance with Kaidan?
But BioWare removed it when ME1 premiered, but not all lines are remowed...
M/M romance with Kaidan in ME1 was never written.
I made a Male shepard just for any male romance options, I really hope Garrus is an option.
Doesn't seem like it. It appears that you can't start new romances with ME2 love interests, to begin with.
James: Gracias. Well, I think I better get back to the hangar. Things here are just a little too soft for me.
Shepard: The bed's a lot harder than it looks.
James: Are you flirting with me, Commander? Thanks again, Loco.
Shepard: Anytime.
"Are you flirting with me, Commander?" and "Thanks again, Loco" are two different lines in the files.
So this is deceptive and not a real indication of M/M Vega.
