An eavesdropping Sharon is stunned by what she hears on Friday's Fair City on RTÉ One and the RTÉ Player.
The St Patrick's Day drama in Carrigstown sees Rafferty and Tommy arguing on the site about Zak's stolen equipment.
"What am I supposed to say if the guards rock up at my doorstep?!" asks Rafferty angrily. "'Oh, I didn't know the gear was stolen. Oh, and the fella who supplied it has gone missing'."
Enter Sharon.
Fans can find out what happens next on Friday on RTÉ One and the RTÉ Player at 7:30pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays and Fridays.
