Kirby and Feras will inevitably be brought back, together I might add. They’re probably going to be advertised as the modern George and Hayley in years to come.
Caroline could return, it would make sense but I don’t think the audience likes her that much.
I feel like Valeria is a lock, considering she was one of the main characters and was voted out by a controversially unfair twist.
Mark and Eden maybe ?
Alex could, I’m not sure what TEN’s attitude is towards only fans users. I’m sure there’s big leaks out there of other players (actually I do know that for a fact). Producers would probably love to reunite him with Kelli.
Everyone else would only ever get a spot if there was spots to fill if they do an all stars too soon again.
Oh, and Raymond. He could come back, for who knows what reason. But I don’t think it’s an impossibility. But the ones who are for sure returning are set in stone I think.
