I don't think either of them will walk, unless BB have confirmed that they'll still get their fee. I'm sure there are a lot of conversations with producers we don't see (we didn't see the resolution to the diary room chat last night. We saw them in there saying they wanted to leave, then it cut to them being back in the 'toxic room'). There's a reason they didn't show the full chat. It wouldn't surprise me if Jeremy is evicted tonight and Steph comes out with him during the live show, causing high drama/headlines etc etc. It would be much better for the show than them both quietly going out the diary room door in the middle of the night. Maybe I'm being cynical
