Lily Chao will have a crisis of conscience in tonight's Casualty after getting close to an ailing patient by the name of Bridget (played by Sian Phillips).

Scenes to be shown this evening will see Lily decide not to strike alongside her ED colleagues. But the prickly physician will change her mind after Bridget encourages her to live for the moment.

Lily then downs her stethoscope and walks out mid-way through her shift - but will she opt to hold a placard on the picket line with Cal et al?

Tonight's other key development sees Iain grow tired of Gemma's destructive behaviour before telling her to pack her bags. His devastated sister then takes Iain's car and speeds off - with disastrous consequences...

All will be revealed tonight at 8.10pm on BBC1.
