Carol and Dolores take centre stage in Sunday's Fair City on RTÉ One and the RTÉ Player.
It's all part of the drama involving Carol's cancer battle.
The medical centre blundered Carol's test results - and Dolores tried to cover it up.
On Sunday, Carol arrives into McCoy's and asks Dolores to hold one of her crutches.
She then slaps Dolores across the face.
Fans can watch what happens next on Sunday on RTÉ One and the RTÉ Player at 8:00pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
