Here's who I would like to see return (in no particular order) in a future season: Ezekiel (Normal and lasting until at LEAST the Final Six), Eva (getting VERY far as a villain but NOT winning!), Noah (Potential Final Three Fail-Win), Katie and Sadie (preferably on separate teams), Tyler, Izzy/Explosivo! (For the ROFL's!), Cody (only to see how his relationship with Sierra is turning out), Courtney (just so she can be voted off FIRST!!!!), Harold, Trent (to see him on a season WITHOUT Gwen), Bridgette, LaShawna (For some redemption for what happened in season 3), Heather (as a good source of drama), Owen (to prove that he's more than just fat), Blainely (so she can prove that she IS the CPN5 Goddess that we all KNOW she is!), Sierra (without Cameron and MOSTLY without Cody), Alejandro (just so he can be BETRAYED by Eva), Dakota (Normal), B (so that he can FINALLY speak), Anne Maria (Without Mike/Vito), Brick (to see a possible Jo/Brick romance blossom), Jo (same reason as Brick), Sam (he STILL needs more screen-time), Scott, Zoey (Without Mike), Lightning (just so he can be voted off EARLY again!!!!), Leonard (to see if he actually HAS some skills), Rodney (to see if he can FINALLY get a girlfriend), Samey (so she can be in a season WITHOUT Amy), Ella (to see her do more than just sing), Dave (potential villain as a result of Sky rejecting him), Max (to see how well he would fare in a season WITHOUT Scarlett), Jasmine, Sugar (because I would like to see how she would react with the first and second generation contestants), and Sky (to see how she would fare against Dave and having to deal with the consequences of her earlier decisions.)
Enough said!
