Emmerdale's Moira Dingle gets the shock of her life when she comes face-to-face with her estranged brother Mackenzie in upcoming scenes.
Now, actress Natalie J. Robb has teased why her character has never mentioned her secret brother before now.
Residents, like viewers, will be stunned to learn the farmer has a sibling, and he's soon causing trouble in the village.
But there's a "dark" family secret brewing, which is all linked to the reason Moira has never mentioned him or her family on the ITV soap before.
Speaking to Mirror online and other press, Natalie teased what could soon come to light as Mackenzie heads back into her life after so many years.
Natalie also hinted that something linked to her past caused her to flee many years ago, suggesting she could have a fight on her hands over the truth about her former life.
She told us: "It's a dark past she's had, and it was a long time ago that she left her family which will be revealed in time.
"It’s something she had to run away from and never look back, in order to continue with her future, if she was to have any future."

On Mackenzie's arrival, she went on: "It's the fact he has turned up in the village and it's such a shock, because it’s been such a long time since she’s seen him.
"He was her little shadow when they were younger and it comes flooding back for her.
"There's a maternal feeling if anything, but he doesn't feel the same way, which is a shock for her."
Moira will be upset to learn her brother despises her, adding: "It hurts her deeply because there’s things that will be revealed and unraveled."
"All she wants to do is give him a big cuddle, and just tell him everything is gonna be alright, and I think if anything it’s gonna take a long time because of what happened in their past.
"It’s deeply hurt Mackenzie, and he's not willing to forgive."
On delving into her side of the family for the first time, Natalie said: "We talked about it for quite a while and it was knowing when the right time was gonna be.
"It’s good because it may explain a lot of why she is the way she is, and perhaps why she is so fiercely protective of her children.
"It's nice to have that link in the past, it's the past catching up with her."
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
