Celia was a co-worker of Billy Campbell, who was a staff writer at the magazine where they worked. They frequently exchanged banter, as Celia was quite annoyed Billy at the onset of their meeting.
Weeks later, Billy and Celia were both up for the same promotion as a junior editor and Billy won out over Celia. Billy then moved to New York, quit the job, and returned to try to reclaim his old job. Celia was upset with him because they wouldn't give her the job because he gave the L.A. office a bad name.
