Gwen could work in this season too. You could have her end up with Duncan instead of Trent since I have doubts on him being in this season. Plus her storyline of a defrosting ice queen works best here.

Harold can also work due to being Duncan's rival.

I would've suggested Lindsay too but Lightning already fills the role of the ditz so she's out.
