In response to the homosexual characters, is Lyn Corbray and Paxter Redwyne also considered to be gay? When they're mentioned it's hinted they prefer boys
Well, while Catelyn says Lyn is “notoriously uninterested” in the charms of women, Littlefinger notes that Corbray is specifically interested in “boys”. Combine that with not hearing about any adult male lovers of Corbray’s (not something GRRM has shied away from when he wanted to hint at it - look at the companions of Laenor and Daeron), and I think it’s safe to say Corbray is more a pedophile than gay.
As for Redwyne, what you’re referring to is a show-only line.
