User blog comment:ScorpioTheBadGuy/Speculating The Season 6 Returnees Of Total Drama/@comment-25297892-20150819090841

First thing I disagree about is your idea on the 4 RR racers: definitely, your affermation doesn't make much sense, RR is a SPIN OFF not a canon series. Also, I think we should count the new RR characters considering that a TD character competing (Noah) will have a story with one of them, so he's likely to return in a season future and sure we'll see in season 6 some of RR characters. Also, Trent and Eva are unlikely to return, the former because we all know that, after 4 seasons he's missing, he was completely forgotten and 99% of his reason to return would be related on Gwen, while Eva, similarly to Justin with Alejandro, has been replaced and overwhelmed by Jo in characterization.

You can debate they could Always do development on Eva and Trent, but judging how lazy they have become by TDAS, either will derail or simply treat as the same way these characters...
