Aw, snap! We love when old characters drop by Mystic Falls — and like producers have been teasing for weeks, somebody we thought we’d never see again is coming to town (and it ain’t Santa Claus!).

According to sources on The Vampire Diaries set, Elena’s biological dad, John Gilbert (played by actor David Anders), is coming back in Episode 2.13, which is set to air in the new year. And he knows how to kill Elijah — the evil vampire after his daughter. Um, that’s huge news! We’re not sure how long he’ll be on the show, but we know it’s gonna be a good with a plotline like that.

Last time we saw Mr. Gilbert, he was heading out of Mystic Falls after Stefan strong-armed him out of Elena’s life — right after Stefan ordered John to give that special ring of his to Jeremy.

We thought his part was done-zo, but we’re so glad it’s not! We can’t wait to find out what John knows about Elijah. We think he might be a real game-changer in Mystic Falls. As if he wasn’t already!
