The Vampire Diaries

In "The Return" (season 2 episode 1), Jeremy asks John Gilbert why the protection ring didn't save his father in the car accident that killed his parents, and John explains that their death wasn't caused by a supernatural event. In the flashback scene in this episode with Elena and her parents under water after the crash, it's clear that Grayson isn't wearing the protection ring at all.

Goof: Near the beginning of the episode, Elena and Damon are talking at the police station. During the conversation, Elena's ponytail alternates between being straight back and being on her shoulder as the camera angle changes.

Goof: In the scene after Damon turns Abby, Esther and Finn disappear from inside of the circle and Kol, Klaus, and Elijah are standing next to each other outside the circle. Immediately after the flames go out, Kol is in the middle of this circle, away from Elijah and Klaus.

Torrey DeVitto, who plays Dr. Meredith Fell, is married to Paul Wesley (Stefan) in real life.

Goof: In the last scene of the episode where Damon and Elena are in bed, after Elena says 'There's nothing more important than the bond of family', Damon moves to his side with his hands under his head. But when Elena turns off the light and the camera angle changes, Damon is on his back with his arms above his head.

At the end of the episode, Damon is wearing his ring on the middle finger of his left hand. In the previous seasons, he typically wore his ring on the ring finger of his left hand.
