Mafia 84. Memorized it, turned it in, forgot it!

Potato blocked Alexeagle. Even though there's nothing about potatoes in the description, the description intuitively resembles a block (Alex was locked in a room -> couldn't perform a night action). Besides, in this mafia game, the only night actions that are displayed are kill, block, and protect the botanist. Of these three, block clearly fits best. Something like that.
