I assume that Duncan is in this group because he is in a scene in the trailer with Gwen and Courtney. But I assume that he's voted off first and that will make Cody basically immune being the only male and Sierra immune by being new. Courtney seems to be the leader so I am going to predict that Heather and Gwen both leave before the merge.
Yes, I still believe that Zeke is a contestant because of the trailer. And it looks to me like they are trying to make people believe that he isn't in or will be voted off early. But he is clearly in making me think that he will last a while. And in the elimination ceremony it will be DJ who gets the axe. I also think that this will be the worst team because all the characters except Zeke have gotten a ton of character development already. I am going to say that DJ, LeShawna, and Harold will all be gone before the merge.
I predict this to be the best team since they are already at a disadvantage at 5 people. Izzy is immune for being the only girl and Alejandro is safe for being new and a villain. I think Noah is also fine since he needs character development and is a fan favorite. I predict that Owen is the only one to be voted off from the team. If they lose another time, it will be Tyler but I think he will last to around the merge.
Merged Team: (Prediction only) Cody Sierra Courtney Bridgette Ezekiel Lindsay Noah Alejandro Tyler Izzy
I think they will merge at the Top 10 or Top 9. If it is the Top 9, I think it will be Lindsay or Tyler that leaves before the merge. Either way, they will be the first 2 to leave. Then Ezekiel might leave, I don't know how far they are willing to go with him followed by Courtney who has already gotten far enough. She may leave before Zeke though. This will leave Noah, Sierra, Cody, Alejandro, Izzy, and Bridgette. I think Sierra will leave here since both the new contestants can't go too far. Then Noah unfortunately since he doesn't have as much winner potential. Here I actually think Alejandro will leave because it will make the Final 2 less predictable. This will leave Cody, Bridgette, and Izzy. I think Bridgette will leave here. Cody and Izzy would be very evenly matched if it were put to a vote, but I think Izzy would win.
Long and detailed prediction I know, but I'm really excited for TDM. I really wish we would just find out when it airs!
