Plot summary
Bonnie's condition worsens as her first scab appears. Damon and Enzo work out a deal with Rayna in which if they kill all the enlisted vampires in her murder list, Rayna will allow them to utilize her last Everlasting's life and help out Bonnie. Over the last 3 years, Bonnie and Enzo have become a couple. Bonnie has not yet forgiven Damon; he does most of the dirty work but remains an uninvited guest to Bonnie and Enzo. Stefan goes to Dallas trying to make amends for how he left things with Caroline but neither her nor Alaric are interested in bridging back their old friendship with Stefan.
Just as Damon and Enzo are close to sealing the end of their deal, Rayna adds hundreds of more names to the list leaving an impossible task ahead of them as they only have a week to kill them all before Bonnie succumbs to the effects of those poisonous pills.
