I think we'll have to RP to see how Herrick gets along with him. There are things about him that Herrick will think are ridiculous bu things that he could also find laudable.
Ele is pretty indifferent towards humans unless they want to be friends and braid each other's hair.
Felix has yet to meet someone he actually likes but if Skye is generous he'll at least like him because he gives him stuff
and he can meet Killian because Killian is friends with Silas. I'm guessing Killian would be interested in his background but he finds it difficult to take people who like vampires seriously. Although I don't get the impression that he's like that. So we'll see.
