As Sarah and Gary cover up Theo's death, 5 Coronation Street theories on what happens next

Theory Briefing

• Sarah Platt killing Theo Silverton on screen was a rare move for the soap, making the cover-up the central dramatic engine rather than a whodunit.
• Gary and Sarah working together to hide the death sets up a classic two-person secret — the more people who know, the faster it tends to fall apart.
• Fan theories are already circulating about who exposes the cover-up, suggesting the show is deliberately seeding clues about the next twist.
• Cover-up storylines in soaps typically hinge on a single overlooked detail — the question is what Coronation Street has already planted without viewers noticing.
