Cain taunts a miserable Robert who is drowning his sorrows over Katie, and when Cain takes things too far Robert snaps and a brawl ensues. Sadie intervenes by telling Cain that his gripe should be with her and she demands that he leave Robert alone. Cain later bursts in on a startled Sadie as she composes herself in the toilets. Matthew witnesses Cain's underhand behaviour and goes to his sister-in-law's rescue. Elsewhere, Chas joins Carl and his son for a game of football and the chemistry between them is more apparent than ever.
