hmmm,
much of the other thread will still apply to your reasoning in such situation, but you can try and retrieve both hands as there should only be 4 cards face-up in the muck pile, the players should be able to tell you what they had, and other players can assist with what they think the players tabled.
If there is any disagreement asto who's cards are who and no agreement can be made, I would leave the money in for the next hand.
