See, this 'Anders was categorically non bi in Awakenings' confuses me.
Because, you know, in DAO Zev definitely stated a preference for women (regardless of how we feel about that), and yet he was still bi.
I don't know about you, but when I meet people they don't necessarily feel the need to sit me down and say, 'hey, catabuca, before we become friends I think I'd better tell you about my sexual preferences. You know, just in case you hear me saying I find someone sexy, you'd better know that I like men and women, just so you don't start thinking I only like one or the other.' You know, there are actual real life bisexual people who express an interest publicly for one particular gender while still keeping their attraction for the other gender somewhat private or for close friends only. It's true. There are many different reasons for that, but there you go.
Snark aside, it really doesn't matter how much Anders expressed his lust towards women in Awakening, the fact remains he didn't once say "Hi, I'm Anders and I am only attracted to women and I am definitely not attracted to men." Without that clarification, it's all to play for. Anything else is just basing it on a feeling you had while playing Awakening. And if we're basing the probability of Anders being bi on our feelings, then it's still all to play for, because there are some of us who felt he was straight, there are others of us who felt he was bi.
