|“||It's okay. I mean, to be honest, I always knew. It's just that, you know, we... we had these moments where we were... just... (sighs) perfectly in sync. You know, laughing at the kids or... in tears because we were so exhausted, I... I guess, uh... I don't know, I guess a part of me thought that maybe, one day, those moments might become something more. But that wouldn't be fair to you. Certainly wouldn't be fair to me, either.||”|
This is the former romantic relationship between the former Enhanced Original vampire/current human Alaric Saltzman and the vampire Caroline Forbes. Their relationship started off as a non-romantic and non-friendship teacher-and-student relationship and has developed on a friendship basis throughout the series. After Alaric's former fiancée died while being pregnant with Alaric's and her twins the Gemini Coven found a way to transfer the twins into Caroline and she gave birth to them. Caroline started loving the twins as they were their own children and helped Alaric raise them. Thus Caroline and Alaric became much closer and perhaps developed deep romantic interest which is indicated by the two getting engaged some time between the flashforward that took place in Season Seven.
After Stefan left Caroline she and Alaric moved into one house with their children. Caroline used to find excuses to sneak out and cry by herself until she started getting home too late and Alaric followed her. Something changed Caroline and she stopped caring about Stefan and focused on Alaric and the two little girls. Eventually Alaric fell in love with Caroline and proposed to her however Caroline does not return those feelings but said yes because it would be the best for Lizzie and Josie.
Throughout The Vampire Diaries Series
In The Murder of One, Caroline helped babysit Alaric while he was dealing with his dark alter-ego that developed after dying too many times while wearing the Gilbert ring. While they were together, Caroline admitted that Elena told her about his current condition and that he killed her father when the darkness had taken over him. Alaric profusely apologized for what he had done and told her he didn't know what else to say, but Caroline pointed out that she had blood on her hands, too, and that the person she killed could have been someone's father as well, which is why she couldn't judge him for it.
In Before Sunset, Alaric, after Esther turned him into an Enhanced Original vampire with the intention of harnessing his dark side and using it to rid the world of vampires, captured Caroline to lure Elena to the high school. While there, Alaric tortured Caroline by putting a vervain-soaked gag in her mouth and stabbing her in the hands with pencils until Klaus, Damon, and Stefan arrived to rescue both girls from him.
In I'll Remember, they were seen hanging out at a diner together, where Alaric brought Caroline books to help them figure out how to reverse the Travelers' Magic Purification Spell that covered Mystic Falls and prevented the vampires from entering the town's borders. While there, the two discussed their lives since being forced to leave their homes and since Damon and Bonnie's deaths, as well as how difficult it was for all of them to be separated from one another.
In Yellow Ledbetter, Caroline met up with Alaric again at the diner to rant about how angry she was that Stefan had lied to them about searching for a way to bring Bonnie and Damon back to life. Alaric informed her that he had been feeding Stefan leads for months, and that he had claimed that he was checking them out. When Caroline angrily reminded him that no one else was trying to help Damon and Bonnie, Alaric admitted that Enzo was still researching into it.
In Hello, Brother, Alaric shows up at Caroline's house to see their twin daughters. Alaric then brings up the idea of moving back in together, which Caroline heavily rejects. They then discuss the stress it's put on both of them to raise their children, especially with Alaric at work and Caroline's ongoing relationship with Stefan. Caroline rejects the idea of moving in together again, mentioning Stefan while doing so. This leaves Alaric disappointed, and this even shows that he still really cares about her (possibly in a romantic sense still), before heading back to the Armory to further investigate the creature's vault.
In Coming Home Was a Mistake, Caroline and Alaric are first seen together with the rest of their friends at Tyler's first funeral attempt. When Damon ambushes it, threatens to kill them all, and then tries to kill Matt Donovan as revenge for Matt trying to shoot him in the back, both Alaric and Caroline and the rest of them try to reason with Damon and stop him from killing Matt. Stefan manages to convince Damon to let Matt go, but Damon flees shortly after this.
After Caroline saves Stefan by shooting Damon with a vervain gun to knock him out, Alaric gets to enjoy spending time with Caroline and the rest of their friends at the empty carnival at Mystic Falls. However, this ends when Matt tells Caroline and Alaric about Seline (Alaric and Caroline's daughters' nanny) being the second siren, both Alaric and Caroline frantically rush home. Alaric and Caroline find the house empty with only a childish drawing of their two daughters holding hands with Seline, next to Cade, the deceased psychic who runs Hell. Caroline looks up from the drawing with a frantic look on her face as the scene fades.
In Detoured On Some Random Backwoods Path to Hell, Caroline and Alaric are first seen together at the house, which was now a crime scene being their daughters were kidnapped by Seline and Sybil. Caroline fusses about it, which leads into an argument between Alaric and Caroline. Alaric tells her off by saying that she brings darkness wherever she goes due to her vampire nature and that he is taking the kids when he finds them. Caroline is shocked and hurt that he would say this being she loves their daughters, but Alaric then retorts that their daughters are his daughters. Alaric emphasized what he meant by saying the Josie and Lizzie was Jo and his' daughters. Alaric then stops himself from talking to her out of frustration, leaving Caroline near tears.
Later on, after they meet up again after finding their kids, Caroline attempts to apologize for her involvement with Stefan and Damon lately, but Alaric cuts her off by saying that he is sorry. Alaric then explains that he was in the wrong for dismissing her motherly status and Caroline smiles, silently accepting his apology. However, Caroline comes to the decision that her being involved with their kids is not the best idea right now, much to Caroline's heartbreak. Alaric seemingly respects her decision and stays silent on the matter before parting ways for now, on the episode.
