It would be pretty amusing to see Trent and Courtney pretend to be a couple just to get Gwen and Duncan jealous. That could branch out into several different scenarios by itself.

Ultimately, if Gwen and Duncan do hook up, I don't think it'll last through the season. As you said, they'll likely go back to their original crushes after they realize that they're a better fit for them. After all, "absence makes the heart grow fonder"!
