The Vampire Diaries - Spoiler From TV Guide - 31st October 2014

The Vampire Diaries' BFFs Bonnie, Caroline and Elena are finally reuniting — in a flashback! The trio will appear together in the show's midseason finale.

In the episode, Bonnie (Kat Graham), Caroline (Candice Accola) and Elena (Nina Dobrev) return to their high school days in a flashback set in the show's first season in 2009. The scene will feature a big holiday gathering, and since we were on hand for the filming, we can promise an impressively festive set. Unfortunately, it's too soon to tell whether the girls are looking back on happier times or if Caroline and Elena are reminiscing about their long-gone best friend. But, if history has shown, the most joyful of Vampire Diaries events tend to end in a bloody massacre. (RIP Mayor Lockwood!)
