Tony and Diane share a dance.
It was announced in February that the actor had decided to end her stint on the soap, with the exit storyline for the much-loved character seeing her diagnosed with terminal stage-four ovarian cancer.
As Diane's final week begins, she confides in husband Tony, telling him that she fears Ro is bottling up his emotions again. At Ste and Rex's pre-wedding dinner at The Dog, Nancy Osborne exchanges some stolen glances with her struggling friend.
Elsewhere, trouble is looming as Ro attempts to drown his sorrows at The Hutch, with the following day seeing the wedding of Ste Hay and Rex Gallagher take place. As the guests try to keep spirits high, Tony whisks Diane up for an emotional dance to their favourite song.
In Diane's final episode, which airs on Wednesday 13 May, Diane records nursery rhymes for her daughter Eva. Knowing she is approaching the end of her life, she reflects on the happy memories of her time in the village.
Tony praises Ro for being brave, and the family decide to bring food to Diane as she rests upstairs. Meanwhile, the Osbornes and Keanes start feuding again, so Leela decides to tear a strip off Beth.
When Tony puts Diane to bed, she thanks him for their dance today, and Diane asks Tony to leave the door open. As Diane listens to Tony and her teenagers singing a nursery rhyme to Eva to get her to sleep, she passes away peacefully.
