Ah I see.
Well, this is how I would do it. The Super Seer is the equalizer. He can only vote to lynch whichever side is winning (has more). This means he can only vote for whoever he has scanned in the past and has confirmed their faction.
Initially he will be voting to lynch the good side but later will be voting to lynch both sides and thin them out. If both sides are equal then he can vote either one.
