When he mentioned not hurting anyone, Caroline was quick to emphasize the point with a determined nod. The last thing she wanted was to repeat her first day as a vampire; the warm, gushing hot blood flowing through the puncture wound in the vulnerable neck was tempting to any vampire, even Caroline-who possessed a strange amount of control for a young vampire-and even now her fangs ached at the sound of his heart beat, signalling the precious blood pumping through his veins. Yet, Caroline held herself back, maintaining her human facade with a strange, unusual easiness, especially considering how little she'd had to eat within the past few days...within the past few weeks actually.
Of course, Caroline owed a lot of her control to Stefan, which was ironic because Stefan was known for being a human blood addict and having little to no control at all once back on it. He was known as the "Ripper" back in the day for his ferocious, unstoppable and unyielding appetite for human blood. He'd drain a body and is such a violent way that the head would be completely ripped off, sometimes more than that. When he taught Caroline control, he was obviously not on a junkie blood binge. The most important thing he taught her? To recognize humans, people, as who they were and what they were: people with names, families, and not food. Not prey, but people. Humanization was the most valuable lesson you could teach a vampire. The value of their humanity, of continuing to be connected to the human world, and what they were, was unmatched and unmeasurable. If Stefan had not been the first person Caroline met-or one of the first-after her transformation, she might never have learned it. She almost didn't; Damon Salvatore wanted to stake her when her transformation into the undead was discovered.
