These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Les Yay: Implied after the Mayor's wife kisses Rose's cheek.
Moral Event Horizon: Cane doesn't actually cross this until he shoots the Mayor's wife (he was aiming for the Mayor, but still...)
