Coronation Street actor Jonathan Howard has shared details about the upcoming conclusion of Debbie Webster's dementia storyline, as the character prepares for what may be her final Christmas with her family. Debbie, played by Sue Devaney, was diagnosed with young-onset dementia earlier this year, marking the start of a long-running narrative that will eventually lead to her departure from the fictional town of Weatherfield. Jonathan, who portrays Debbie's son Carl, confirmed that Sue is under contract with ITV until August 2027, but the storyline is being built up for emotional impact as Debbie's condition progresses. Speaking exclusively to The Sun at the Inside Soap Awards 2026, Jonathan said that Sue is contracted to stay until August, but the dementia storyline is intensifying, with scenes expected to be very sad. He expressed his deep emotional connection to Sue, saying he is happy she gets to play his mother and has always felt supported by her. He noted that the cast recently had lunch together, including Michael Le Vell (Kevin Webster) and Sally Carman (Abi), highlighting the close-knit family dynamic they have created. However, he admitted it is sad to know the storyline will eventually come to an end, even though it is still a year away. The Websters are set to experience an emotional festive period as they become increasingly aware of how precious their time with Debbie is. Jonathan revealed that the cast has received their Christmas scripts, which coincide with Carl's 40th birthday. The scripts suggest that this might be Debbie's last Christmas, as there is a sense that this could be the last time she is fully herself. Debbie's dementia storyline has already brought significant changes for the character and her loved ones as they grapple with the diagnosis and its implications for their future. The storyline will unfold gradually over the coming months, keeping Debbie at the center of the Webster family until next year. News of Debbie's eventual departure was first announced last year, sparking a strong reaction from viewers. Debbie has become a fan favorite since Sue returned to the show permanently in 2019, with some even launching petitions to keep her on the show. Sue confirmed at the National Television Awards that leaving Coronation Street was not her own plan, explaining she was happy at Corrie after recently getting married and not wanting to go on tour. However, she ultimately decided to embrace the opportunity the storyline presented, emphasizing the importance of her role as an actor. She also expressed gratitude for the viewer response, noting that it meant she had been doing something right. Sue mentioned she had infused Debbie with her own "mums-isms" and unique sayings, which she was delighted to see appreciated by fans. Meanwhile, there are more developments in the Webster family before Debbie's final chapter. Jonathan teased further drama involving Carl, Kevin, and Abi following the fallout from Carl's affair with his brother's wife. He hinted that there will be tension between the three, with one of them being left out, adding to the emotional complexity of the family's journey.
