The worst play of the game goes to Trent, because it is never acceptable to rage-quit a game and then ruin it in the way he did. Rage-quit fine. But to out the scum team like that makes him an asshole.
But Meda's play wasn't far off. Lying to Town, claiming to have answered questions that she was dodging all game until deadline approached and she had to be lynched. Furthermore, a good player would have realized not to have used the "lovers" ability in the first place. That gaining a chat with someone at the expense that both of you die together was a bad trade. And it's not like "lovers" confirmed her alignment anyway.
My advice to Gamma, don't try to soft claim like that. All it did was tell scum for sure you were Vengeful (and probably the Tracker) while the rest of us thought you were squirming. If you feel you have to drop a claim, claim it. That way Town can assess the lack of any counter-claims.
