During their stay in the Desert Otherworld, Kevin appeared to be quite fond of Carlos and was genuinely distressed upon reading the note Carlos left for Kevin at the radio station. Kevin is quite fond of Charles and thinks he is incredibly handsome. Additionally, they both like playing guitar so it's not unlikely that they would get along well. Kevin has been known to fall in love with someone he meets only once before leaving home. This happened when he met Lara at the radio station while searching for his parents. Although she was married at the time, he fell in love with her and didn't stop thinking about her after he left. Years later, she was killed by Drogo when she was just a young girl. Now, given how fond he seems to be of Carlos, it may be possible that he could end up doing the same thing with him.
