Leo is left horrified as Dean makes a revelation in Tuesday's Fair City on RTÉ One and the RTÉ Player.
In Tuesday's episode, Dean says he wants to spend a few thousand doing up Will Casey's grave, much to Leo's bemusement.
The villainous Will was the ex-husband of Dean's partner Mairéad and the father of Mairéad's daughter Phoebe.
His violent death caused shockwaves in Carrigstown in September 2021.
In Thursday's episode, Dean shares a secret with dad Leo.
"I know who did it," says Dean.
Fans can watch what happens next on Tuesday on RTÉ One and the RTÉ Player at 8:00pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
