Roll again, twice. You are both those roles. If you get this one again, reroll.
If your alignments conflict, you are the last alignment you rolled. If one of your roles is Vanilla or Goon but the other isn't, you are the other role.
Examples:
1) Vanilla Town and Mafia Goon. You are a Mafia Goon.
2) Town Doctor and Mafia Goon. You are a Mafia Doctor.
3) Town Vigilante and Town Doctor. You are town, and you both shoot and protect your target from one kill.
