Unpopular opinion and maybe it's just me but I don't think Callum did let it slip
.He said he wanted to get a friendship with Molly at the very least coming out of the villa, he never said he knew she was going to be there. Once he knew she was there, then he wanted a friendship as a minimum. That is how I interpret his interview, and I think their reactions when she walked in were too genuine for them to have known. Maybe their agents/management knew but that's a different story.

100% Needs to take a break, they ruined X Factor year on year and making it more scripted etc to keep up with the success over the previous years. It needs a complete overhaul with a fresh presenter, fresh challenges, organic drama without the fear of being cancelled (this is why they apologise so quickly afterwards through fear of being hated) and re-couplings and contestants that are relatable and down to earth, not these fame hungry influencers. Where are the same sex couples? Liberty was the only girl bigger than size 10, where are the people that are our age 30+ and look like us? This is why the first seasons where the best!
