It's all eyes on Dearbhla and Gar in Thursday's Fair City on RTÉ One and the RTÉ Player.
Teeing up what's ahead, Fair City says: "Dearbhla insists her fling with Dean was a one-night stand and pleads with Gar to give her another chance."
However, things take a turn for the worse when Gar confronts Dearbhla and says: "You need to stop lying."
"Gar?" says Dearbhla.
"I know it wasn't a one-night stand with Dean," he continues.
"It was!" protests Dearbhla.
"Then why has he got nudes of you on his phone?" says Gar.
"I'm sorry, what?" says a stunned Dearbhla.
"Fergal told me," says Gar.
"Is this a sick joke?" asks Dearbhla.
Fans can find out what happens next on Thursday on RTÉ One and the RTÉ Player at 8:30pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, and Thursdays.
