Someone said they saw him hinting toward Dragon Age fandom. Which DEAR GOD PLEASE NO. Bioware fandom is already completely and totally fucked up. Otoh, it's also pretty incestuous, so I doubt he'd be able to hide there long.

It would have to be something with serious slash potential, but Andy doesn't seem drawn to things that actually have male characters kissing each other canonically, so that also (hopefully) would be a mark against him going for Bioware. I'd guess Sherlock or Hannibal.
