Kevin was rarely, if ever, put in situations that required anyone’s protection, so Dimas didn’t really get to show that side of himself. Dimas was another story, though. He stuck out like a sore thumb amongst people who’d been systematically taught all their lives that the nail that sticks out gets hammered down, and so people were often unkind to him. That’s not to say he didn’t get along with anyone in DB—he was friends with a number of Kevin’s interns, most of his colleagues, and got along fairly well with Lauren—but his presence generally evoked an unwelcoming atmosphere, largely because many people in Desert Bluffs operated under the assumption that the opinion Kevin broadcasted in his first encounter with Dimas was the ‘correct’ one.
Consequently, if anyone ever ‘flirted’ with Dimas, it was usually mean-spirited and done in an effort to make him feel uncomfortable or self-conscious. Kevin did not tolerate this sort of thing at all, and while he rarely responded with outright violence, he did make a few broadcasts that ended with several individuals being seriously injured. So yes, Kevin was very protective, especially since Dimas stopped sticking up for himself after a few months of being constantly worn down.
A few times Dimas garnered genuine interest, and though he wasn’t always aware it was flirting, it put him in a better mindset when people were suddenly nicer to him. As a result, Kevin didn’t really get jealous—since he’d directly contributed to the cultivation of the mindset that made Dimas feel like an outsider, it was always a relief to see people treating Dimas like he belonged.
