It was honestly a struggle to decide whether Jakob should bear the gay or bi flag... really it's trying to pigeonhole something that's more of a spectrum. Ultimately his current preferences are a lot closer to gay, so I've gone with that for simplicity's sake. 'Cubi tend to be pretty relaxed about sexuality anyhow.
