The doctor will soon be in once again.

Absent for all of The Vampire Diaries Season 4 so far, Torrey DeVitto (who will be a series regular on Season 7 of Lifetime's Army Wives) will finally reprise her role as Meredith Fell on the February 21 installment of our favorite CW thriller.

It's titled "Stand By Me" and it will be the final TVD episode until March 14. How will the show leave us hanging off a cliff for those few weeks?

Read through the just-released official synopsis for the episode, welcome Meredith back and start to wonder about these mysterious plans set to take place...

When Stefan arrives back in Mystic Falls with Elena and Jeremy, Caroline is immediately worried about Elena’s state of mind. Stefan reaches out to Dr. Fell and Matt for help. Still on the island, Damon relays somber news to Rebekah and is surprised at her reaction. Together, Damon and Rebekah learn an unexpected bit of recent history from Vaughn (guest star Charlie Bewley). Everyone is horrified when Bonnie reveals the rest of Shane’s plan. Finally, after Damon does his best to help her, Elena comes up with a plan of her own.
