User blog comment:KKirby/Total Drama World Tour: What if Alejandro was a Hero and Sierra was a Villain?/@comment-35606925-20191012173813

Hmmm...this is intresting. I'm not sure where you intend to take this, but my guess would be a Sierra vs Cody finale.

As for Duncan coming back, I think he needs to. While people might hate the love triangle, it's such an important part of Total Drama World Tour that I don't think it can be ignored.
