Bonnie
Bonnie and Cole actually went to high school together, but they were never close. Cole kept his distance from most people and while Bonnie would have happily been his friend, he had no interest in friendship with her. It was complete coinicidence that they both happened to be interviewing for a job at the same place (one of Cole's worst nightmares is seeing someone from high school at a place like this). Once they both started working together though, Bonnie wouldn't let them stay acquaintances. This is a good thing for Cole though, and he realizes that he does like her and he thinks of her as one of his last threads to the surface world. He also thinks of her as naive and overly kind and he is constantly worrying over her safety. Things always seem to work out for her though!
Pig 
Pig is Cole's number one best friend, they've been through everything together! Cole doesn't know how Pig ended up in DDL ith him but he sure is happy that he's here. The kindest and happiest you are ever likely to see Cole is when he's with his dog. He's always been a very diligent owner and on the surface Cole used to go on walks let Pig pull him along on his longboard. Cole seems completely oblivious to how strange is dog really is though...
The Director 
Cole... isn't sure how he feels about the Director. He is afraid of him but at the same time, through observing Bonnie's interactions with him, he seems to understand that the Director isn't as bad as he could be. He's not really sure that he respects the man either, after getting closer to him the more he realizes the flimsy the Director's grasp on being a boss truly is and he's come to realize that Grey is the true glue that keeps things together.
Double Cross 
He doesn't like DC's jokes, doesn't like his personality, doesn't like his ideas of fun, and yet the two seem to spend a lot of time together. Mainly it's because Cross is one of the few "people" down here that Cole isn't afraid of and although he's unlikable hes so normal that being around him can be a bit of relief for Cole, especially since Bonnie can be so overbearing.
Grey 
Cole is usually terrified of all supernatural creatures but for some reason Grey doesn't freak him out like everyone else does... Oddly Cole finds Grey kind of cute and thinks of Grey as a friend more than a superior (this is hardly mutual). Cole likes to share earthling passtimes with Grey as well, like Gameboys and trying to throw pencils so that they get stuck in the perforated ceiling tiles.
