A little knowledge is a corrosive thing in Tuesday's Fair City on RTÉ One and the RTÉ Player.
Zoe tells her sister Kelly: "Alex and Dearbhla were being awful secretive in the kitchen earlier."
"They had a thing once," Kelly sighs.
As she sees the shock on Zoe's face, Kelly continues: "Not for long - I think it was a one-night-only deal."
Fans can find out what happens next on RTÉ One and the RTÉ Player on Tuesday at 8:00pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
