Meanwhile, Hollyoaks fans can expect fireworks when the real Lisa Loveday makes her mark on the village.
Lisa, played by former X Factor star Rachel Adedeji, will finally be tracked down this fortnight - but this time Louis and Simone are taking no chances and insist on a DNA test to be sure.
When it's officially confirmed that Lisa is the right girl, it all becomes too much for her so she rushes off away from her parents - and straight into the fake Lisa.
Lisa lashes out when she hears about Sonia (Kiza Deen) stealing her life, forcing Zack to step in when the heated clash gets out of control.

Afterwards, Zack persuades Lisa to come home and the Lovedays remind her of her life before Margaret took her. However, when Lisa insists that she had a good life and wants to see Margaret, they realise they've got a long battle ahead to earn her trust...
Hollyoaks airs these scenes on Monday, May 2 at 6.30pm on Channel 4.
