Never said Wesky was gay! (He's not).But Wesker had Excella around his fingers,not the other way around.She had the power at first ,and he had a dream.He sold it wrapped up with his d*** .The box was bad ,Excella was annoyiing and Wesker was greedy...but what if Excella ,WAS compatable? What then?
As for Chris and Piers,it could just be a mentor thing,I ship them for lulz.I won't count that as evidence of homosexuality...but them costumes and his severe lack of interest in women,could be a repressed homosexual.No problem with that.And I really do think Wesker would f*** a dude if there was something to gain from it(say if someone more powerful than him wanted him and seducing him was the only way to get samples from said guy.Wesker would suck it up ,lie down and think of england).He likely treats sex with anyone that way.Hell,dude probably don't even beat off,or if he do it's urges and no fantasies.
