Stop Being Polite puts up “official” cast list post. Basically, it’ll be updated when more information is found. Given that Jordan & Tori are coming back, maybe it’ll be a couples season? Also: no Hunter. You think he managed to win WotW? Or piss off BMP?
ETA current list: Cara Maria, finalist Georgia, Georgia we haven't met yet, Johnny, Jordan, Josh, Killa Kam, Kyle (him and Cara? Super), Nany, Paulie (him with Cara AND Kyle? Fuck), Rogan (I still think interns tackled him at the start of Vendettas, lest he eliminated Johnny), Bear (my fear: England bars him from coming back, and he becomes the problem of the United States), Theo (already the second-best Theo in Challenge history), Tori (I haven't dove into her relationship with Jordan. I hear they collaborate on songs. Maybe I should check that out).
Thinking about it, maybe Rogan would be there to sacrifice upon an altar. How else do you summon Turbo?
