Nikki counsels Mondo in Sunday's Fair City on RTÉ One and the RTÉ Player.
As his trial date over the death of Anto nears, Mondo has split up with Kira and has spent the night with his ex, Melanie.
Now, Mondo is wracked with more guilt - and Nikki is trying to provide support.
"You're a good man," says Nikki.
"Sleeping with Melanie?" replies Mondo.
"Is it the real thing?" asks Nikki.
Fans can watch 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.
