THE TEAM WORKS WITH RAYNA TO SAVE BONNIE'S LIFE — When Enzo's efforts to protect Bonnie end up putting her life in jeopardy, they learn that Rayna may hold the key to her survival. With time running out and Rayna at the reins, Enzo and Bonnie reluctantly team up with Damon, who is desperate to save Bonnie's life and to repair their broken friendship. Elsewhere, when Stefan travels to Dallas and comes face to face with Alaric, tensions escalate and they are forced to confront the fallout from Stefan's absence in Caroline's life. Finally, Enzo learns The Armory's true motives behind their search for Bonnie.
- "Bonnie still carries around Damon's letter unopened as a reminder of why she shouldn't trust people," Plec says. 
- Several days have passed since the events with Stefan getting back control of his own body from Ambrose this according to Stefan to Alaric as they talk in the diner.
- Damon makes a bargain with Rayna Cruz to hunt down and kill the vampire souls that were formally in the Phoenix Stone in exchange for her help to save Bonnie's life.

Behind the ScenesEdit
- On April 1, 2016, the press release for this episode revealed its title to be "Time, As a Symptom". However, it was later changed, and the actual title was revealed.
- The first time they rehearsed the New Years Eve scene, Grismer had the Billie Holiday song play out loud for the whole cast and crew while Kat and Michael danced. Everyone was so moved. One of the crew members came up to Holly Brix with tears in her eyes. She wanted Holly to know how much she loved seeing Bonnie get a epic love story.
- The cabin is the same cabin built for Stefan a.k.a. Marty’s no-good-very-bad-horrible day in “I Went to the Woods.” Some paint and a genius redesign by our art department and brilliant Set Decorator Karen Brucks, and it’s a whole new set.
- Co-writer Matt D’Ambrosio had a bout with appendicitis mere days before he was supposed to go to Atlanta to watch filming. After an emergency appendectomy and permission from his doctor, he got on a plane in time for the last half of the shoot. Matt, incidentally, started TVD in season 1 as an office PA in the Atlanta production office. He mentioned his dream of being a writer to producer Pascal, who suggested we move Matt to L.A. to work in the writer’s office when a position opened up. Since then, Matt has been the writers’ assistant and is currently the script coordinator.
- Malarkey taught Kat how to play guitar for her scenes.
- We cast a really big stunt guy to be our vampire in the dentist office and so a special body dummy had to be flown in from Canada so that it would match his actual size. Joe Props had to go and pick the dummy up at the airport as if he were a relative flying in.
- Paul Wesley and Matt Davis had a lot of scenes together in this episode where they’d argue and then Alaric would walk away from Stefan at the end of the scene. So Matt got in the groove of ad-libbing “I’ll be in the car” as his parting remark which would make Paul laugh every single time. He’d tell him not to do it and Matt would promise that he wouldn’t, but then he would and Paul would laugh again. He just couldn’t keep it together.
- Hashtag during the airing is #Bonenzo
- "Somebody That I Used to Know" was the second single by the Belgian-Australian singer, Gotye, which features vocals by Kimbra, on the album Making Mirrors. The song was released on July 5, 2011.

- Damon: "We would be happy to wipe out anyone off your list."
- Alaric: "Now Care and the girls left in a hurry. Trying to stay under the radar until this Rayna thing blows over."
- Stefan: "No. No. It's..it's nice."
- Alaric: "Yeah thanks. You'd be amazed what you can accomplish when your fiancé can compel an interior designer and an entire home owner's association."
- Stefan: "Thought you were out of the game."
- Alaric: "What do you mean?"
- Stefan: "Well the...supernatural world."
- Alaric: "Oh yeah. We are. Have you ever dealt with the home owner's association?"
- Stefan: "No. No. Can't say that I have."
- Alaric: "Oh look, uh I'd offer you something but...I haven't been to the store for a while. So unless you want a juice box, some stringed cheese, I'd suggest you look somewhere else."
- Stefan: "I'll probably get something stronger."
- Damon: "What if you had a little help? Brooming out those runaway prisoners: A hit squad if you will."
- Rayna: "I'm listening."
- Rayna: "Those vampires could be anywhere! You better get started"
