Fergal inflicts more psychological trauma on Dean and Dearbhla in Tuesday's Fair City on RTÉ One and the RTÉ Player.
Dean has become the target of an elaborate revenge plan by the unhinged Fergal - with Fergal catfishing Dean by pretending to be a woman called Vicky.
On Tuesday, Fergal takes control of Dean's email and threatens to send intimate videos out to his contacts if Dean refuses to play his sick game.
Later in the community centre, Dean declares his love for Dearbhla as Fergal watches on smiling.
"Dearbhla, I love you," says Dean. "And, em, just the thought of your amazing body keeps me up all night..."
Fans can find out what happens next on Tuesday on RTÉ One and the RTÉ Player at 8:00pm.
