Don't forget to thank Colonel Mustard as well, since we all know Mustard and Peacock were working together.
In round 2, Mustard ignored the Lounge because he knew Peacock already had that evidence.
In round 3, Peacock ignored the Ballroom because she knew Mustard already had that evidence.
In round 4, Mustard gets a free pass to the billiard room, but would've ended up there anyway I suppose.
In round 5, Mustard suggests Peacock in the Billiard room in order to pull her into those hard to reach rooms, all the way from the Lounge, "because the mustard desires company". Indeed.
At no point in the game did Peacock suggest evidence held by Mustard. Mustard did suggest two pieces of evidence Peacock held. Once in round 5 when he helped Peacock reach the Billiard Room and thus wasn't making a serious suggestion anyway, and once in round 6 when he was apparently just making a random suggestion to intentionally fail so that Peacock could make the serious suggestion and win.
So let's hear it for the team of Mustard & Peacock. We've finally put an end to this interminable game. And can move on to Game 2. And this time, hopefully get players that won't bail on us, get washed away by flooding, or who are personally involved with each other (had I known this beforehand, I would have raised an objection) and thus can't actually be trusted not to share info.
