Fair City's Will uses mind games on daughter Phoebe on Thursday night on RTÉ One - but how will the youngster react to his ultimatum?
When Will and Phoebe meet for a chat it's not long before he shows his nasty side yet again.
"Why is it so easy for you to be mean to people?" asks Phoebe.
"Well, where's that coming from?" says a shocked Will.
"All this stirring about Caoimhe and Damien - all it's going to do is hurt mum," replies Phoebe. "And even if they do break up then what? She'll meet someone else you don't like.
"You don't want her back, do you? So is she not allowed be with anyone else?"
"Phoebe, what are you on about?" says Will. "Right, this isn't about other people. Right now all that I care about is getting her away from Damien."
"Why?" says Phoebe. "He's not that bad."
"He is dangerous," says Will. "I hate to say this but you need to grow up a bit. Phoebe, this is serious. I'm trying to protect your mother. Now you're either with me or you're against me..."
Fans can find out what happens next on Thursday on RTÉ One at 8:00pm.
Fair City airs on RTÉ One on Sundays and Tuesdays to Thursdays.
