EastEnders star James Bye has teased a very turbulent time ahead for his character Martin Fowler.
Martin's life has been thrown into jeopardy since his partner Stacey Branning gave birth to baby Arthur over the Christmas period and immediately started suffering from postpartum psychosis.
Martin remains torn over how to best support both her and their son in coming episodes, but, of course, viewers know that his best friend Kush Kazemi is actually the biological father of the newborn.
Appearing on This Morning today (January 19), Bye discussed the challenging psychosis storyline and also hinted at more twists ahead for Martin.
Speaking about the baby plot, he said: "It's EastEnders so it is going to come out. I can't say whether we have filmed it or not because I will get an enormous slap on my wrists.
"It gets layered on quite thick for Martin and it just keeps going and going. More things happen to him until the reveal.
"I am interested to see how they are going to do it. I've said this before but it will be a sink or swim moment for him."
Bye also praised the enormous amount of research that went into ensuring that Stacey's storyline was handled sensitively.
He said: "The research team at EastEnders have been incredible. We have managed to work with some of the charities like Mind and met these two incredible women who opened their stories up to me and Lacey [Turner].
"We had a long chat and they are just so brave to be able to do that and to tell us some really personal stuff.
"When you get stories like this, I think Dom sat me and Lacey down and said, 'So you're going to have a child and he's going to be the son of God'.
"You wonder how you are going to make it work and then you meet these women and they have been through so much more. It really helps to bring it to life."
