Returning/Coming:
Alejandro (New character and looks to be the villain. I wonder if he's related to Justin, taking off his shirt and all)
Bridgette (Looks like Geoff got full of himself and she was the only one to move on. Good, this will give her a chance to shine more)
Cody (Great that he's back, it looks like he will have a lot of character development with the new female character. He could go a long way)
Courtney (This gives her a better chance of winning since Beth isn't in the season)
Duncan (He's made it far two seasons in a row. I'm not sure how long he'll be able to keep it up)
DJ (This is chance to redeem himself after the secret alliance with Chef, I hope he does well)
Ezekiel (I am really scared he will be the first voted out, there are various scenes without him and it could be a running gag)
Gwen (No Trent this time, this could be interesting)
Harold (This gives him a better chance of winning with Beth not in the season)
Heather (Maybe with this new guy being the villain, and a season break, she'll do some secret things and surprise everyone again)
Izzy (And she comes back again! I wonder how many times she'll return this season
)
LeShawna (She seems to be regaining the plot with Harold, I don't think that she'll last really long though)
Lindsay (No Beth this time to help her along, she'll be fending for herself most of the time)
Noah (I think he could go really far, the producers know he is a fan favorite. And a character who was voted off so early needs character development)
Owen (I imagine that he'll make it about half way again, the producer's love his character, but he has already had plenty of development.
Tyler (In the last episode of TDI, I thought his character was getting a lot better. So I'm glad that he gets another chance. We all thought that the plot with him and Lindsay was over. But maybe not, she has mentioned him in this season)
Unnamed Female Contestant (Possible love interest for Cody and looks really crazy, she could have a plot with Izzy since they both are like that)
Not Returning:
Beth (Due to this, I'm starting to doubt her winning. It's not impossible for her to win and not come back, but Owen did. So I don't know)
Eva (Appeared once in the preview but not in the group shots. I expect the other characters to have a bigger role this season than last.)
Geoff (He was getting arrogant, so he needs some time away from the show and Bridgette)
Justin (Makes sense, his plot will probably run out by the end of this season. But as I said before, Alejandro could be related to him)
Katie & Sadie (Both annoying. I think that Katie had potential and Sadie didn't. And they didn't want to separate the two.
Trent (Same as Eva. This doesn't come as a huge surprise to me. Trent was popular, but there really wasn't much else that could have been done with his character)
