There's drama ahead on Fair City when Orla and Wayne are rocked by Sash's decision. Get a sneak peek at the episode here.

Coming up in Wednesday night's Fair City, Sash is having second thoughts about being a surrogate for Orla and Wayne.

"Well what about Tommy?" Sash asks them. "He'll be passing his own child in the street not even knowing it's his?"

"What he doesn't know can't hurt him," Wayne retorts.

"Secrets get out!" Sash fires back. "I don't need to tell the two of you that."

"Sash, please don't do this," Orla begs.

"I want a baby more than anything, it just can't be this one. I can't go ahead with it. I'm sorry, I really am," Sash tells them, leaving Orla and Wayne stunned.
