I love how the reason Emma’s brash plans work in the moment is because all the other human and demon players are operating on roughly the same psychological level, where all players are at all times fully aware of each piece on the playing board, and both sides will be think of the same moves and counter moves that can be made, delaying the moves of either side, because neither side is going to react in erratic ways without considering all the consequences of their actions, and this is assured because both sides think so similarly.
And then there’s Emma who’s just like “I’m going to do the thing,” and no one ever expects it because she’s not playing or think of all the rules that all the other players are bound by.
