That would've made the character more interesting
Or maybe she could've spent a few years in England and killed on her way back home, so she might have an accent
Her speaking in a british accent would be..idek droolworthy
But killing her off after
she has been away from home would not work.
It was kinda the point the end of her life was the beginning. She could not break out while she was alive, Chuck had to die first and brought back to life by her childhood sweetheart
