EastEnders' Stacey Slater faces a battle to save her mother Jean on the BBC soap on Thursday night, as events take a worrying turn.
Jean, who suffers from bipolar disorder, is in the middle of a mental health crisis and Stacey has urged others to realise this for weeks.
Stacey has tried to help her mum and tried to get her the help she needs, but Jean believes she's fine despite acting out of character.
