Tommy steels himself for what's coming next in Sunday's Fair City on RTÉ One and the RTÉ Player.
The drama involves Joan trying to connect with her long-lost son Gar - her latest attempt ending in disappointment.
"If you pull another stunt like today, you're only going to make things worse," Tommy warns Joan.
"Which is why I need your help," Joan replies. "You're my last hope."
Fans can find out what happens next on Sunday 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.
