So let's say that my opponent (I refuse to acknowledge I'm married to her for this argument) has Stupid Station Eismette in play, as well as some unnamed OVERPOWERED Explorers, probably brought into play with stupid ULTIMA THULE. I play a Deranged Diva. I target her and drive Deranged Diva insane. She now has to make someone insane right? Even if all she has is a dumb Explorer that has no Willpower? The triggered ability targetted the player, NOT the character, so I'm hoping she, er, my opponent, doesn't have a peg leg to stand on.
EDIT: My opponent, thinking this is relevant information, wants people to know that this would not have changed the outcome of this game. He/she may be right; I still would've forfeited to Antarctic Explorers from Hell.
