Cain's relationship with the others:
- Alak - Cain doesn't like Alak; he doesn't like the way Alak looks, the way he acts, the way he speaks; if it were for Cain, Alak shouldn't even exist; even so he has to tolerate Alak and to supress his constant desire to murder Alak
- Aleksy - Cain is pretty neutral when it comes to Aleksy; there are a few things that he linkes and others that he doesn't, but all in all Aleksy isn't a person Cain bothers a lot with
- Aoi - Cain is pretty indifferent towards Aoi; since Aoi never causes any trouble nor is he the source of any entertainment, Cain is fine with things the way they are
- Cecil - Cain prefers to not aknowledge Cecil's presence when he's around; there are some people Cain prefers to avoid rather than start a fight with and one of those people is Cecil
- Damien - Cain doesn't care much about Damien; even so, he tends to get competitive when business things are involved, always trying to best her when it comes to holding events
- Elyon - Cain continues to be amazed by Elyon's patience with him; he's aware that he can get on her nerves and sometimes makes efforts to keep calm around her, as he values her skills as well as her as a person greatly
- Illya - Cain doesn't care that Illya is considered a paria by his fellow warlocks; he cares about Illya's hard work and his natural charm that brings clients to his bar
- Kara - Cain had a friends with benefits relationship with Kara for a few years; there were no feelings involved for him, everything being purely physical; he has no regrets about what happened with her and is glad that he didn't get involved emotionally
- Kieren - Cain doesn't care much about Kieren; he is aware that Kieren is scared of him and prefers for things to remain that way, knowing very well he wouldn't be able to handle Kieren's bubbly personality otherwise
- Klaus - Klaus gets on Cain's nerves more often than not but Cain never acts on his anger; even if he rarely shows it, Cain is fond of Klaus and his chaotic nature, considering it a good form of entertainment
- Marshall - Cain sees Marshall as the glue that keeps the family together; he appreciates Marshall's quick wit and his way of making communication work even in the hardest moments; although Marshall can get on Cain's nerves quite easily, he can never stay angry with him for too long
- Mina - Cain's frendship with Mina is a long lasting one, with him considering her part of his family; Cain feels at ease around her, making him appreciate her easy-going, although insecure, personality
- Mollymawk - Cain finds Mollymawk to be too weak and caring for his liking; Cain doesn't care about interacting with Mollymawk, nor does he have any desire to know him better
- Nathan - Although Cain disliked Nath at first he now considers him his best friend; after being through highs and lows together, Cain knows he can trust Nath completely with anything; Cain considers Nath as part of his family and he would do anything for his friend
- Novalie - Even to his own surprise, Cain doesn't mind Novalie; he tolerates her more than he tolerates most others, probably because she knows how to make herself likable without being pushy
- Selene
- Stephan - Cain is mostly indifferend about Stephan; as long as he doesn't start fights at his bar and doesn't mix with the people Cain cares about, he has no reason to dislike Stephan
- Viola - It took time and patience for Cain to love Viola; at first he found her annoying and not someone he planned to spend his life with; now he is grateful that she didn't give up on him, as he feels he is more open and more understanding of humanity than how he was before she came into his life
- Yulya - Although Cain finds Yulya very attractive, he knows better than to get involved with someone like her; as far as it goes, he is fine with just admiring her from afar
- Alak - Cain doesn't like Alak; he doesn't like the way Alak looks, the way he acts, the way he speaks; if it were for Cain, Alak shouldn't even exist; even so he has to tolerate Alak and to supress his constant desire to murder Alak
