What are the total drama action couples?

The Total Drama Island couples are:

Duncan and Courtney

Tyler and Lindsey

Trent and Gwen

Geoff and Bridgette

Cody and Beth {maybe, they did kiss}

Owen and Izzy

Harold and LeShawna

*Katie and Sadie like Justin. Cody likes Gwen. Ezekiel likes Bridgette. SPOILER: Justin starts to like Courtney in Total Drama Action.

SPOILER: In Total Drama Action, though, there is a twist between Duncan, Gwen, and Trent. Trent and Gwen end up breaking up because Trent is throwing matches for her, and because he was creeping her out with the whole "9" thing. As a result, Trent got kicked off because of Gwen. Gwen and Duncan are seen flirting and Duncan wrestled her to the ground.

SPOILER- in total drama world tour, Duncan and Gwen become a couple, Sierra has a major crush on Cody, and Heather and Alejandro like each other (they sort of become a couple)
