I have a hard time seeing them announcing either the Winner or Loser first, since that would tell the other where they placed, and the look on their face would be hard to hide (Winner looking way too happy or Loser looking pissed). It would give away The Mole.

Show The Mole first, then reveal which Player won. At least, that's how I'd do it.

And I don't remember anyone celebrating that someone got Executed. Shock and $*+$% were the norm, I though.
