What's going on with you two?
We kissed. Now it's weird.

So says Damon to Bonnie in the following clip from "The Ties That Bind," Thursday's all-new episode of The Vampire Diaries.

As the official promo makes clear, this installment will feature the return of Abby Bennett, the birth mother Bonnie has not seen in 15 years. Can she help her daughter open the mysterious, locked coffin hiding out in the old witches' house? That's the plan/hope.

Get an early look at the episode below, as Bonnie and Elena sort through paperwork and then Damon comes in to rescue the day... as only he can.
