When Phil shows up on the doorstep incandescent with rage, Reiss has no choice but to tell Sonia that he's meant to be paying Phil back but can't. Teddy and Sharon manage to calm Phil down and Sonia buys more time by appealing to Sharon. Later, Teddy makes an offer to pay Phil and take over Reiss's debt - Reiss shakes on it, but is there a catch?

Cindy catches Gina trying to get into Junior's phone and she admits that she's trying to find out who her brother's mystery woman is. Later, Cindy's nose gets out of joint when Junior fails to show for a secret meet-up, only to arrive at The Vic to find him introducing a date to the family.

Also: Kathy returns from the States and informs Phil that Ben is in a bad way, while Harvey runs himself ragged trying to earn extra money to give to Maya.

Cindy tries to blank Junior when Gina reveals that he slept with Maxine last night. Junior accuses Cindy of overreacting but she makes it clear - if he wants to be with her, then he can't sleep with anyone else.

At the baby scan, Sonia tells Reiss that it was madness to agree to a deal with Teddy, someone they hardly know. Meanwhile, the police arrive at the café and start asking questions about Reiss and Debbie.

Martin tips off Reiss about the police's enquiries, causing him to have a panic attack.

Sonia manages to calm Reiss down and they head over to The Vic for their engagement party - but things come to an abrupt end when the police arrive and arrest both Sonia and Reiss for Debbie's murder.

Also: An exhausted Harvey falls asleep in a hot car with baby Charli in the back, while Chelsea moves out of No.1 as the new owners move in - it's Teddy, who's bought the place for him and his boys.
