Calum Christopher doesn't do well with people. However, he's learning. See, Calum understands people perfectly. He understands psychology in a creepy way, but that's his job and he needs to. He sets traps, His friends are few, and his enemies plentiful. Calum plans attacks and is excellent at strategy. He's awkward and intelligent. If he could pick a best friend from any T.V. show ever, Dr. Spencer Reid would be his first and only choice. Fact, he's a skin-walker not a werewolf. Mostly similar but somewhat different. He doesn't just disclose this fact either. (If you watch Supernatural you will have a finite understanding of the species.)
