If roxie self-targeted doctor for some reason (I doubt it) the protected one wouldn't be HH?We know Roxie couldn't have been self-targeting Doc, BG, or Crusader because those would've resulted in Roxie not dying. I think that leaves the options for Roxie as:
Lookout
Trapper
Ambusher - if one of the visitors had defense
Recon
Disguiser
Forger (but self targeting n1 would be really weird)
