Continuity mistake: Frederick picks up a bottle of champagne out of the ice bucket and shakes it a little. As he does this the foil and wire are still on top. He turns and aims the bottle at his wife, then tips it back and the foil has vanished as he now just removes the wire and cork.






Chosen answer: Frederick knew that Trent was his wife's lover. That's why Trent was invited. The party was supposed to be an opportunity for Frederick to take revenge.
