Original in Gotham ~ victor zsasz

"Isabel he's dangerous"
"oh because a thousand year old vampire who can't be killed isn't?"

What happens when the Mikaelson sister visits Gotham to see her old friend Jim after the death of her twin brother kol?
Especially after a certain hitman takes interest in her and doesn't leave her alone

I suck at descriptions lol but I'm a fan of the vampire diaries and Gotham and wanted to put them together :)

This is my first story so sorry for any mistakes oops
