@Tdilover7: That's actually a very plausible scenario, and one that I hadn't anticipated before. Duncan kisses Gwen not because he actually has feelings for her, but because he wants to get back at Courtney following a fight over Duncan supposedly spending too much time with Gwen. Now that's a scenario that could provide a lot of drama!

Plus it wouldn't be the first time that he's tried to make Courtney jealous before. Remember in Get a Clue when he smirked deviously after seeing Courtney gasp when Lindsay chose Duncan as her partner for the movie reward? He knew it would make Courtney jealous, so he went along with Lindsay's plan. >:D
