|“|| Damon: Just you?

The relationship between cured vampire Damon Salvatore and the deceased vampire Enzo St. John. They were both test subjects for the Augustine Society, they formed a strong bond during their years of captivity. You could say that Damon and Enzo are a mixture of good and bad. Due to many set backs in their relationship, they aren't as close as they used to be and are currently frenemies, but they still remain allies.
However, at the end of the seventh season, Enzo and Damon were captured by the Armory's creature and they are currently killing people together in order to help feed the creature and bringing it back to its possible, initial form. This brings them closer as Stefan and Bonnie continue to try and save them.
They are known as "Denzo" by fans.
In 1953, when Damon was captured by Dr. Whitmore, he met Enzo. Damon is thrown into a cell where Enzo is first seen, he tells Damon to "pick yourself up, soldier" before introducing himself. After telling him that they have one glass of blood per day, he tells Damon he is doing it wrong; he is living for the moment when he should be living of the future, the future when they can extract their revenge. His revenge would be "killing Whitmore's dog and mailing it to his house", asking Damon to then picture his own.
Damon and Enzo's friendship grows through their time in captivity, Enzo is seen asking Damon about his interests, revealing his own is Jaguar cars which he can take out to impress women. Damon tells him that the one woman he was trying to impress was more of a "Horse and carriage" type of girl. After Damon asks about any women he has met, Enzo tells him about Maggie, a woman he met while in captivity. She knew nothing about the torture of vampires however when she found out, she couldn't bear it and left. Damon suggests the relationship between a vampire and human wouldn't of worked out and it was for the best, Enzo smiles and says "he needs a more positive outlook" before Dr Whitmore walks in asking who is next.
He heads towards Damon saying he looks as if he has more energy however Enzo quickly speaks, saying he is far more energetic, sparing Damon from the torture that day. As screams are heard throughout the basement, Damon angrily paces his cell. When Enzo is returned, bloody, Damon demands to know why they are doing this to them.
After the one night of the year they are let out of the cells, a New Years Eve party Dr. Whitmore hosts to show his findings, Enzo came up with a plan for their escape. As they are given one glass of blood, if one were to have two a day, the vampire could build up their strength for the next party so they would be ready to fight. After a game of "rock, paper and scissors", Damon wins and drinks Enzo's rations for a year.
One year later, Damon is pulled out from the cage although this time, after drinking Enzo's rations is able to break the chains. He kills Dr. Whitmore and the rest of the guests at the party, however a candle is knocked over and as Damon tries to break the cage bars, he cannot due to vervain. The flames begin to take over and as Damon realizes he cannot free Enzo, he shuts off his emotions before leaving.

Damon refused to fight Enzo and Enzo then desiccated mid fight. Damon injects Enzo with many antidotes and one of them works. Then, Damon reaches inside Enzo's chest and tells him he had to flip off his humanity to leave him. Enzo tells Damon that he was the most important person in his life and he ruined him and that he is just a monster and always will be.
In The Devil Inside, Enzo showed up at Damon's house with Aaron in a body bag. Enzo told Damon that he had done some "soul searching" and was quick to judge him. He told Damon that he wanted to see if the Damon he remembered was still there, to show him he asked Damon if he wanted to kill Aaron. When Aaron woke up instead of killing him, Damon snapped Enzo's neck and told Aaron to leave. Later, Enzo was lying in the road when Aaron stopped. Enzo said Damon was teaching him a game. After Damon and Aaron argue that Elena was too good for Damon and that he is a monster (which Damon confirms) he bites and kills Aaron much to Enzo's delight. "There's the Damon Salvatore I remember", and they both smile over Aaron's dead body, their friendship completely renewed.

They open the door and find they are stuck inside—and Wes Maxfield is there. Damon is his patient zero and he wants to see how long Damon can go before he feeds on his best friend. They're trapped. Enzo is worried seeing as Damon can't go eight hours without killing. Damon assures him he's not going to feed on him. Back at the farmhouse, Enzo chains Damon to a chair (with his permission). Then Enzo calls for back-up. "I told you your pride isn't worth either of our lives," Enzo says to Damon's objections.
He calls Stefan, but Stefan isn't near his phone and Katherine answers. Enzo catches her up to speed as Damon shouts in the background for them not to come. Katherine tells him to text her the address and they'll be on their way. He tells her he's under strict orders to kill Damon if he tries to feed on her. He's kidding but it gives her an idea. At the farmhouse, Damon is worried he'll feed on them if they come. Suddenly, there's a shot. Wes shot Enzo in the shoulder to see if Damon would get hungry enough at the smell of his blood to break the chains.
Damon busts through easily and attacks Enzo. Enzo tries to remain calm and yells at Damon to stop. Finally, Damon pulls off and starts retching.

You're not a brother to him. Brothers don't give up. So every time I see you doing anything that looks like you've done so, every time you try to start over in a life that's nothing but a lie, I will make you pay. I will be the one to bring you the misery you deserve.", then Enzo snaps Stefan's neck.

- Damon: "Yeah that'll do it."
- Enzo: "See? Now that's what I call a missed opportunity. Perfect time to tell your brother you're hanging up your fangs for a pair of khakis."
- Damon: "No idea what you're talking about."
- Enzo: "Yes, you do. I might have plied Alaric with enough alcohol to slur the news into my ear."
- Damon: "Well, you are the last person who gets to criticize me for withholding information, my brother from the same mother. You ever gonna tell me Lily turned you?"
- Enzo: "Yeah, once you mastered the art of returning phone calls."

- Enzo: "What, with the prospect of taking the cure? No point in agonizing-- you won't go through with it."
- Damon: "Says who?"
- Enzo: "You! You're selfish, Damon. Being human isn't what you really want. I mean, don't get me wrong, I like that about you. A man should be consistent. But, take it from someone who you left to burn to death in order to save your own skin-- no one changes that much. Not even under the magical influence of Elena Gilbert. Anyway, cheers, mate."
