Vampire Diaries season 6 may soon give the biggest shock to its fans in episode 13 which is titled 'Prayer For The Dying'.

The upcoming episode will not be easy to watch as it is Bonnie's birthday, and she is still trapped in the Mystic Falls of 1994.

Elena and Damon will try to convince Jeremy to celebrate her birthday, while they all try to fit the pieces of the broken ascendant back together to send a message to the Bennett witch. However, they realise that their dear friend is planning to commit suicide.

Stefan, on the other hand, is helping Caroline to overcome the bad phase she is going through and this will bring them closer to each other.

Episode 13 will also focus on Sarah Salvatore and her great grand uncle Stefan.

The official synopsis of TVD's upcoming episode titled 'Prayer For The Dying' reads:

"HAPPY BIRTHDAY, BONNIE — Determined to celebrate Bonnie's (Kat Graham) birthday, Elena (Nina Dobrev) convinces Jeremy (Steven R. McQueen) that it's what Bonnie would have wanted. After piecing the broken ascendant back together, Elena, Jeremy and Damon (Ian Somerhalder) attempt to send Bonnie a message, but the situation turns dire when they make an unsettling discovery. Meanwhile, after uncovering Stefan's (Paul Wesley) secret about his great-niece Sarah Salvatore (guest star Tristan Mays), Enzo (Michael Malarkey) enlists a reluctant Matt (Zach Roerig) to help interfere with her life. Elsewhere, Stefan keeps a close eye on Caroline (Candice Accola) as she unconventionally attempts to cope with everything going on around her. Lastly, realizing it might be time to move on with his life, Jeremy contemplates leaving Mystic Falls for good."

Will Delena be able to save their friend from taking the death step? How will the turn of events affect Jeremy in the future?

All questions will be answered when the show returns on the night of 5 February, 2015 on CW network.
