1. Easily fixable. He gets the memo to go to Amrita and Heckity Leaves.
2. Just because he's surrounded by Gods doesn't mean he can't worry about people knowing he's gay. Homophobic gods have to exist. And in a place full of straight peeps, yes, being gay is gonna be a little different, regardless of the interesting things going on with lineage. (Nico's hiding he's trans anyway.)
3./4. Shove the whole Robbie thing back a bit. In Nico's history, Cecilia is supposed to die when she's 16 and Nico 18, but I had to shove that back two years to make room for Amirita. Hell, Nico learning he's trans got shoved back quite a bit too. I'm gonna have to shove back some things in Luc's history too, though I'm not sure which. The suicide attempt most definitely. I might even have to take that part out, even. (Probably not, because that's what leads to his self harm addiction, but I'm sure I could work around it.)
