Katie Killjoy/Relationships

Tom Trench
Tom is Katie's colleague. It is unclear if their relationship is purely professional or not.

Katie tends to get irritated whenever Tom mentions anything of sexual nature. It is possible that she also has a tendency to abuse Tom, seeing that after Tom makes a pun about "nailing" Cherri Bomb, she is seen pouring scalding hot coffee onto his crotch. In reaction to this, Tom can be heard saying "not again", suggesting that something similar has happened to him before, likely also from Katie.

Charlie Magne
"You might be some royal big shot, but that doesn't mean shit to me."

- Killjoy, to Charlie

Katie appears to care nothing for Charlie's status as Princess of Hell, believing that she is "too rich and influential" to do so. She has no reluctance whatsoever in talking Charlie down, and even threatens to "bury" her.

Katie is doubtful about Charlie's plan to help rehabilitate the denizens of hell, seeing it as a joke and even going so far as to ridicule her during an interview. She additionally fights Charlie after having her pen snatched and being called a bitch.
