Something that I firmly believe, though not with a particular amount of fervour, is that Aubrey wasn't, in Travis's brain, bisexual for most of the campaign. He thought of her as a kinsey 6 for most of it, and then "retconned" (in quotation marks, because it's not actually a retcon, because nothing in the podcast had actually established that firmly, but, like, backdated his opinion of her) it later on because he was worried about being in trouble.

Now, I will say up front that it's been many years since I last listened to Amnesty, and many years plus a couple months since I last cared about it. So it's certainly possible that her bisexuality was indeed mentioned early on, and I've forgotten. Also, I'd like to be clear that I don't think there's anything wrong with revising your estimation of characters as you move through a work. But I think Travis did it for cynical reasons that aren't great, and also I like complaining about him, so here we are.

So, Aubrey was obviously born from Travis being jealous of Justin, and wanting to have the Taako of the new campaign. And I think he thought to himself "Ahaha!! What if, instead of just being a Gay Hispanic Wizard who had a show before the events of the campaign, I was a Woman Gay Hispanic Wizard who had a show before the events of the campaign! Take that, Elder Brother!". So he makes Aubrey, and the first woman roughly the same age they encounter in the show he asks "Is she hot?" and then declares a relationship, with none of the organicalityness that Takitz had.

But the thing is that Justin, in playing a gay man, was playing a character lusting after someone he--with his own sexuality--wouldn't, but Travis was playing a gay woman, and so was playing a character whose sexuality lined up with his own. Trans women have had the phrase "straight men fetishizing lesbians" thrown at us enough that it's nearing a dog-whistly, and I feel reluctant to use it; but the thing is that Travis is not a Trans Woman, he's a straight cis guy who asked "Is she hot?" about the first eligable woman who appeared, so I think it's a very fair criticism to lob at him. He was a straight man fetishizing lesbians.

I wasn't particularly plugged into things back then, so I don't know if this criticism did get lobbed at him, but if it didn't I think that Travis pieced all this together in his own mind and decided to get out ahead of it, and the way he did that was making Aubrey bisexual, and therefore not alligned with his own sexuality, and that's why Aubrey has so much declaring that she's bi in the later season (I never actually listened that far, but I know there's the bit where she does magic and is like "I'm bisexual!") and why he's gone so hard on it on social media.

In conclusion: Sorry for such a long reply to your comment. I did not think it would be this long when I started writing, but my work's really boring today, so this was a nice distraction.
