Carol encourages JJ to make up with Steo in Tuesday's Fair City on RTÉ One and the RTÉ Player.
Recently, JJ laughed at Steo's concern about his health - and a hurt Steo then told his father that he was only spending time with him because he thought he was sick.
In Tuesday's visit to Carrigstown, Carol tells JJ: "I would give anything to have even one more day with my son. That's not possible. You're lucky. Do not blow your chance with Steo."
Fans can watch what happens next on Tuesday on RTÉ One and the RTÉ Player at 8:30pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
