User blog comment:CheeseBurgerGuy/Total Drama Theory: What If Gwuncan Was In TDI?/@comment-28092650-20191019205356/@comment-35606925-20191019212407

Honestly, there was a while where I was going to have Gwen make her exit in Basic Straining...but I doubt the writers would've made that drastic of a change.

Duncan will be making more appearances thoughout the season. I'm not quite sure if I'll be bringing Duncan back as a full on contestant though.

Courtney coming back would only complicate things, so don't expect her to return though.
