Tonight's episode sees the couple's surrogate mother Tina McIntyre (Michelle Keegan) give birth two months prematurely, and the new arrival is immediately whisked off to a special care unit as he is having difficulty breathing.
As everyone anxiously waits for news on the youngster's wellbeing, the revelation that Gary (Mikey North) recently made a pass at Tina is the hot topic of discussion.
With Izzy (Cherylee Houston) unable to forgive Gary for what he's done, she rejects his attempts to support her through this difficult time.
Izzy is also disgusted with Katy for failing to tell her what was going on. Can life ever get back to normal for these two troubled families?
