This moment of gay panic really bothered me. If Feral wasn’t Feral, she’d be dead.
I can assure you that Alison would have done the same to any unbreakable guy who force-kissed her!
It was more the, “Oh my god, someone kissed me!” than the, “Oh my god, a girl kissed me!”
This explains why Alison is worried about hurting someone in an intimate moment. Sure, consciously she knows that Feral could survive that, and she knows that she knew that when she did it… but I think she probably wonders whether that actually factored into her reaction or not. And that’s not an easy question to resolve.
