Greg tries to lay down the law with Steo on Tuesday's Fair City on RTÉ One and the RTÉ Player.
Just released from prison, father-to-be Steo is in Carrigstown as he tries to build bridges with Jess, the mother of his child.
Steo and Jess had a secret romance, but she is now in a new relationship with Greg - Steo's best friend.
The tension mounts on Tuesday as Greg tells Steo: "She doesn't want to talk to you."
"I need to hear it from her," Steo replies.
"You're hearing it from me," says Greg.
"Yeah, well, that's not good enough," says Steo.
"Are you saying I'm lying?" asks Greg.
"Maybe she's lying - to you," says Steo.
Fans can find out 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.
