Strictly Come Dancing's week four returned with notable highlights, including Nick Knowles' comeback after a knee injury and his performance of the Charleston, which fans predict may lead to his exit. Sara Davies, a former contestant, was spotted in the audience, showcasing her significant weight loss and cheering for fellow celebrities. Dr. Punam Krishan, paired with Gorka Marquez, performed a Bollywood dance, expressing pride in representing her Indian heritage on such a large platform. As the competition intensifies, viewers continue to debate the perceived advantage of contestants with professional dance training, a point highlighted by Tasha Ghouri who has a background in commercial dance yet finds ballroom challenging. The show combines scores with public votes, and the bottom two pairs face a dance-off, with Paul Merson and Nick Knowles seen as vulnerable.
