Josh told the entire table that he and Oscar had been sleeping together and Jasmine flew off the handle.‌Amid the tears and the screaming, Jasmine made it clear that she did not want to see Josh again. She also told Oscar that she would be willing to give their relationship another shot if he was able to get act like nothing had ever happened with Josh. But, having had a talk with Cindy about how important accountability was, Oscar decided he couldn't do that.‌Later, Oscar and Josh had a conversation in the cafe, where Oscar explained what happened. Josh seemed hopeful that, with their affair out in the open, he and Oscar could be together. He even invited Oscar to go and stay with him and Sandra in Southend.But, Oscar declined and kissed Josh goodbye, telling him he should focus on rebuilding his relationship with Jasmine. After that, Josh picked up his bag and walked out. Josh is sure to be back soon, as his exit was only for the weekend.‌The fallout from the affair reveal has shocked fans. Jasmine threatened to kill Oscar multiple times, before her stepgrandfather Alfie Moon stepped in. Alfie gave Jasmine a hug whilst telling her that she was better than Oscar and Jasmine broke down in tears.Fans said they loved that moment between the two of them. One wrote: "Alfie really knows how to deal with the Slater women as silly as he can be sometimes he can be such a sweet character."Another added: "The only paternal figure being the one who she responds best to, ties into her lore with Kieth and his death. The writing for Jasmine has significantly improved, much better."‌A third continued: "I loved the moment where Alfie was calming Jasmine down. It felt like she had someone who she could trust and feel safe with in that moment, like a parent she didn't have all her life."As for Josh, many fans felt the way he told Jasmine about the affair was selfish, especially after admitting to Oscar that he did it because Jasmine was so "happy". One fan said: "So Josh is just a selfish individual? Got it."‌Another pointed to when Josh tried to suggest he and Oscar make a go of things: "He is he’s a slimy individual I still can’t believe he had the nerve to go back to Oscar and ask him that knowing full well what’s happened earlier like he just doesn’t care what he did to his sister"in my eyes I don’t think I can ever like Josh and Oscar’s character again. Especially Oscar’s the writers ruined his character for me and I just don’t like him anymore."A third said: "'She just looked so happy, Oscar' so I had to take that moment and traumatise her because it was just sooooo unfair..." While a fourth said: "And to think I was starting to feel sorry for Josh and believe he truly felt guilty! But no, he had to invite Oscar to spend the weekend with him because f**k Jasmine and the pain they've caused her, ey?"Article continues belowLike this story?
