Anna and Dolores are stunned when Hughie announces he's taking them to court in Sunday's Fair City on RTÉ One and the RTÉ Player.
It's all part of the drama that saw a distracted Anna make a grave error while treating Hughie - giving him penicillin even though he is allergic.
To make matters worse, Anna's nursing licence is out of date.
Fans can find out what happens next on Sunday on RTÉ One and the RTÉ Player at 8:30pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
