Gwen panics when she learns Nina is snooping into Zak's alleged involvement in the kidnapping in Friday's Fair City on RTÉ One and the RTÉ Player.
Sash tells Gwen: "Zak did a lot of awful things, but kidnapping Carol Foley wasn't one of them."
"He didn't do it!" Sash continues.
"Yeah, he did," Gwen replies as Sash laughs nervously.
Fans can watch 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.
