A: It doesn’t. After getting a related question on this, we realized that this card is not practical for a two player game. If one player left, the remaining player would simply be playing solitaire, taking turns until they won.* That’s no fun. Just remove this card when playing with two people.
*Though it’s certainly possible that the remaining player might have a situation where they’re forced to make the absent player win, that’s fairly rare, and we’d rather just rule that this card is not to be used in a two-player game.
