Fair City is set for a meltdown on Sunday night as Renee, Ellie and Hughie try to cope with Heather.
Things go south on the Northside when Heather is told by Renee that she can't go out with Ellie on her own.
"Will you stop treating me like a baby!" she warns her mother and daughter.
When Renee tells Heather she is not going to Howth, she shouts for Hughie.
He arrives bleary-eyed in the room as Renee orders Heather to pack her things and come home.
"I don't want her coming back!" pleads Ellie. "If she comes back then I'm moving out!"
And when the youngster tells her mother that she ruins everything, Heather screams the house down.
Fans can find out what happens next on Sunday on RTÉ One at 8:00pm.
Fair City airs on RTÉ One on Sundays and Tuesdays to Thursdays.
