Carol warns Lorcan Jr that if he doesn't get his act together, he will have to go back to London in Sunday's Fair City on RTÉ One and the RTÉ Player.
"You don't need to patronise me," Lorcan tells his grandmother as they have words.
"Then act like an adult!" replies Carol. "Or I'll call your ma and get her to come and get you!"
"What and admit you couldn't keep me in line?" says Lorcan.
Fans can watch what happens next on Sunday on RTÉ One and the RTÉ Player at 8:30pm.
