"The Vampire Diaries" returns this week with an all-new episode titled "Kill 'Em All." In the upcoming episode, Bonnie continues to fight for her life and it will be up to Damon and Enzo to save her before her condition takes a turn for the worse.

In last week's episode, titled "Somebody That I Used to Know," Damon and Enzo struck a deal with Rayna. They would kill all the vampires on her murder list, and in exchange, Rayna will use her last dose of EverLasting life to save Bonnie. Damon and Enzo were doing well in accomplishing their goal until Rayna decided to add more than a hundred names to the list.

Now, in "Kill 'Em All," the two will have less than a week to kill all these vampires before Bonnie succumbs to the effects of the poisonous pills that she has been taking.

Earlier this month, actress Kat Graham hinted that the final episodes of the season will be quite monumental for her character Bonnie.

"There's some really intense stuff with my character this season. I think the biggest episodes I've ever had are 20 [airing April 29] and 21 [airing May 6]. It's pretty major for the character — huge turns, a lot of stunts and cool s***!," Graham told US Weekly.

Meanwhile, in order to help Bonnie, Stefan will reluctantly team up with Matt. Through the course of the episode, Stefan will finally uncover the reason for why Matt is so angry at him. To be able kill all the vampires on the list, Caroline and Alaric also join the mission. Caroline will begin to realize just how much he has missed her former supernatural life.

To find out what happens to Bonnie, be sure to catch "Kill 'Em All" airing on Apr. 29.

Season 7 of "The Vampire Diaries" airs every Friday at 8 p.m. ET on The CW.
