He's a joke from fail_fandomanon - basically he's Tyler Hoechlin's fictionalized self, if Tyler Hoechlin was writing Teen Wolf RPF about himself and Dylan O'Brien. I'm not sure if he accidentally migrated there from FFA RPF (he's nominated there too) or if someone nominated him genuinely in Teen Wolf RPF and he wound up being accepted.

It'd allow FFA nonnies to legitimately request Taylor Hartlin/Dylan O'Brien, though, if he stays there! That would make both them and Tyler Hoechlin very happy, heh.
