It is a very nice story and I wouldn't have expected anything else either - there really aren't many bad stories about any of them floating around (not in Swedish sites either). I am thinking that, even though she's saying all the actors from Hemloch Grove were positive, she must have had some not so nice reactions along the way for her to have kept it a secret and for Bill's reaction to have made such a difference, if that makes sense?
Yeah I get it. Well, not generalising but American society is still very homophobic. Imagine how transsexual people get treated then. There must be a reason why gay people don't come out much in the industry leave alone transsexual people. So yeah I guess his reaction was a positive surprise to her.
