Question: what happens in season 5 episode 16 of the vampire diaries?
Answer: Bonnie and Liv arrived at the dorm to find Elena burning everything Katherine had touched. Bonnie told Elena she was letting Katherine win and she couldn't be let out in public like this. Elena pretended to agree, but then threw a makeshift stake at Liv's gut. If she didn't let Elena out to feed her blood, she'd die.
