Nikki gives Maxine some friendly advice in Sunday's Fair City on RTÉ One and the RTÉ Player.
The drama begins when Sash confides to Nikki that Maxine is awkward around Sash's daughter Olivia.
Later, Nikki asks Maxine: "Do you not like kids?"
"No, they're grand," a defensive Maxine replies.
"Well, Sash said that you're acting weird around Olivia," Nikki continues.
"Why is it your business anyway?" says Maxine.
Nikki then tells Maxine to make an effort with Olivia or risk losing Sash.
Fans can watch what happens next on Sunday on RTÉ One and the RTÉ Player at 8:30pm.
