Zoe tears strips off Melanie in Tuesday's Fair City on RTÉ One and the RTÉ Player.
The ructions follow Zoe learning that Melanie was involved in the theft of Hughie's car - a crime that initially saw Zoe in the frame.
On Tuesday, Zoe says to Melanie: "I know everything, you lying, two-faced rat."
Zoe then turns to a gobsmacked Hughie while Claire watches on and says: "Tell her, Hughie."
Fans can find out what happens next on Tuesday 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.
