Leave it to Katherine Pierce to leave that as a parting gift.
Yes - SPOILER ALERT - Katherine truly is dead, but not before proving one final time why she deserves to rot in whatever dark destination has snatched up her corpse:
To conclude The Vampire Diaries Season 5 Episode 15, Katherine left Elena as the latest victim of the Ripper Virus.. the extreme Ripper Virus, that is, thanks to an infusion of werewolf blood.
Where will this leave Elena on The Vampire Diaries Season 5 Episode 16? Out. Of. Control.
