PENNY Branning decides to quit Walford as a shock betrayal is revealed in EastEnders.
The character - played by Kitty Castledine - has had a difficult few months after being involved in the club crush horror at Peggy's.
Penny was desperate to prove she could host a successful club night after taking Chelsea Fox's job, but didn't realise Chelsea had advertised more tickets than were available and safe to sell as part of her plans for revenge.
It meant that the crowds piled in and when it became overcrowded, people were crushed and injured.
This included Penny's half-sister Amy Mitchell, who had covertly got into the club despite being under age.
A paramedic told her dad Jack that she had suffered a cardiac arrest, and she was placed in a coma once at the hospital.

Now in upcoming EastEnders episodes, Amy continues to struggle.
At the hospital, Amy gets upset at the rate of her recovery and an argument between Penny and Amy breaks out.
Later, Penny makes the decision to leave Walford, and arrives at No.27 as Jack and Denise try to buoy Amy up.
