In as far as Steele is a set character (s/he doesn't do some things; outright murder and all that), I think reacting with aversion to a naked picture of your cousin is pretty vanilla. I actually have no stake whatsoever in the romance between them, but I'd like an ending for the rival that isn't "and you shove her out the airlock into the void of space, satisfying the murderboner you've had since day 1". If it has to be sex, whatever.
