Maybe they'll do extra roles like they have in other Mafia style games.
For example, Gaoler. Prevents a person from leaving their room at night. But they don't know if the person they 'jail' tries to leave or not. So if they choose a traitor by chance or design, they can't join in on the nightly discussions. Or Sentry. Detects if the player they pick left their room in the night. This would also apply to all Faithful additional roles as well, so a Faithful gaoler would come back as having left their room.
Would probably be too complex for TV I guess, but it would shake things up a little. Give the Faithful more to go on.
