Playing With / If I Can't Have You

Basic Trope: One character loves another and, upon being rejected, tries to kill them.
Bob: Alice, love, you're going back to If I Can't Have You? Well, that's fine then - wait, you're going to another trope, aren't you? How DARE you betray me?! If you won't edit me, then... I WON'T LET YOU EDIT ANOTHER TROPE IN MY PLACE!!!
