Errmm - she did kiss Clem, on the lips, not a sisterly kiss.
Just read your Trivia entry - nice catch.
I don't think though, that Woodward's the person who gets to decide whether or not Elsie's LGBQ or not by the way, that decision would be the showrunner's. And you notice that scene was cut, removing Woodward's stated motivation for the kiss so it may be that the Nolans wanted it to be ambiguous.
Shame it was cut, that sounds interesting. And I like her comments about it not mattering what sex Elsie is, we really don't see that enough yet.
