But could his secret bring them even closer together?
As Emma and Curtis head to the corner shop to set up for Dev’s photoshoot, Curtis’s phone rings. Making out he’s got a dental appointment, Curtis hurries off leaving Emma to sort out Dev’s photoshoot.
When Debbie lets slip that Curtis is in the bistro with a young girl and looking very cosy, Steve’s concerned and sets off to find out what he’s up to.
In the bistro, Steve approaches Curtis, demanding to know what’s going on and tearing a strip off him, assumes he's cheating on Emma and leaves.
After Curtis tells Emma that it's over between them, Steve finds Emma sobbing in the factory kitchen. Reckoning she's had a lucky escape, Steve confronts Curtis in the bistro, who admits he's got it wrong.
Trusting Steve with his secret, Curtis makes him promise not to tell Emma. Calling at the salon flat, Steve finds Emma in bits and battles with his conscience, aware of the promise he made.
Later, when Curtis reveals that he’s heading out Steve offers to accompany him and Tracy is baffled as she watches Curtis climbing into Steve's taxi. And when she reveals that she saw Steve giving Curtis a lift, Emma is left reeling.
As Steve and Curtis arrive back on the street, Tracy strides towards them demanding answers and Emma realises she does love Curtis after he tells her about his secret heart condition.
Meanwhile, Dev tells Curtis that he wants to pull out of the calendar as it could scupper his chances of joining the golf club. Promising he'll do his best, Curtis fears it's too late. Brandishing the calendar picture at Curtis and Emma, Dev demands they put a stop to the print run.
Whilst Curtis stresses over the calendar, Emma worries about his health.
