Greg's stint as babysitter leads to a world of trouble in Tuesday's Fair City on RTÉ One and the RTÉ Player.
Baby Taylor is at the centre of the Carrigstown drama after falling off a couch.
His birth father, Steo, has complained about Taylor's mother Jess to family services.
On Tuesday, Greg is babysitting Taylor when Dr Olivia Sutton from Tusla visits.
"Can you explain this bruise?" she asks Greg.
"Oh, that? Ah, that's nothing," Greg replies.
"It looks like something," says Dr Sutton. "Do you know how it happened?"
"Jess and Ruby had a fight," says Greg.
"And the baby was caught in the middle?" says Dr Sutton.
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, and Thursdays.
