Tommy is starting to look very cagey in Carrigstown, as he returns from his trip and it emerges that he wasn't in fact in Kilkenny at all. Even Caoimhe is suspicious of her dad. Look, he was just a crazy stalker THAT ONE TIME. It turns out Cathal knows where Tommy has really been, but is quick to plant the seed with Debbie that perhaps Tommy is in fact Katy's captor. Speaking of, Katy does her best to try get her kidnapper on board and forge a connection with him, but will it work?
