You are Elena Gilbert from season 4, no humanity Elena. You had watched your brother Jeremey get killed, and so you turned off your emotions. Damon and Stefan tried the whole day to get you back. They tied you to a chair, took your daylight ring and tortured you with the sun.

Stefan: “This isn’t working, we can’t hurt her, not enough.”

Damon: “Well who hates her enough to torture her… let me think, Katherine.”

Stefan: “You think Katherine would help Elena?”

Damon: “Getting to torture Elena, of course.”
