"The Vampire Diaries" airs a new episode next Friday evening. What can fans expect to come next on The CW network series? The synopsis and an extended promo clip were released. They reveal that Stefan Salvatore (Paul Wesley) will do something drastic to save his brother, Damon Salvatore (Ian Somerhalder). However, Damon might never forgive him for it.

'TVD' season 8, episode 5 synopsis

The synopsis for the next episode of "The Vampire Diaries" reveals that Stefan Salvatore will have to make a difficult decision. This has to do with his brother, Damon.

It isn't revealed what he decides, but the extended promo does tease that he needs to "put him down." What exactly does this mean?

Will Stefan kill Damon in 'The Vampire Diaries'?

When thinking of the phrase "put him down," fans automatically think that Stefan will kill Damon in "TVD." However, there is another theory. Sybil (Nathalie Kelley) told Stefan last week that the only way to save Damon was to make a deal with the devil. That seems unlikely, but maybe Stefan will put Damon somewhere so he is unable to hurt anyone else?

This is the famous carnival episode

Sneak peek photos show this is the carnival episode that people have been talking about for months. Besides an image of "Steroline," pictures show Damon Salvatore manhandling Stefan.

He is angry and takes it out on his brother. What will happen now?

Damon Salvatore is trapped

In the extended promo for "The Vampire Diaries," Damon is seen in the last few seconds trapped behind a glass window. He is banging and screaming in anger. It looks just like the observation room at the Armory where Sybil was taken.

Could Stefan trap his brother and put him in the Armory in order to prevent any more deaths?

What do you think is going to happen next in the long-running television show? Will Stefan kill Damon in "The Vampire Diaries" or does he have another plan? Keep watching The CW network to find out what happens next with Sybil, Caroline Forbes, Bonnie Bennett, Alaric Saltman, and the Salvatore brothers.
