|Courtney's role in the show is to give Duncan a partner, Gwen has Trent, Owen and Izzy, etc. All of the main characters in the show pretty much have relationships. Duncan's personality is the opposite of Courtney's, so they stuck them together. Heather doesn't have one since she was a villain, and Beth/Justin is just Justin's way of having an alliance. |
Courtney was just there for Duncan I believe.
But now, on a certain level, her character has grown outside of the role that was originally designed for her. She's still Duncan's girl, but now she's an overly competitive lawyer monster who's going to trash a lot of people's dreams of a million bucks.
Actually, that's one of the reasons why I started liking Courtney in the first place. She's gotten an entertaining role.
