They're close friends. I like Christian lightyears more than Orangedee, but they definitely seem like the type of people who would hang out together. Like why Caridee gets hired by Heatherette despite being unattractive and pudgy.
^Ah, that explains it. I can see them being friends too, I just just surprised, because I love Christian and think he's really talented. No wonder she got the job (or was it a job? Was it just for fun?)
