Betsy over at Camp McCarran whose into, 'Tall blondes' whom she can 'Jump their pants' (she was butt raped by a fiend). Veronica was apparently in love with a chick back at her old brotherhood compound, the dude at the Mohave station where you have to get a pardon for that imprisoned powder ganger dude (is gay), and that Cpl.
Arcade Gannon is ousted as a homosexual if you have the 'Confirmed Bachelor' perk. As a male character I cannot hit on Cass successfully without her being all defensive but I have the option of sounding like a Legion butt pirate. From playing through the game for hours and reading the different outcomes with some of the companions I was surprised just how 'gay' this game is.
