Holly calls Hayley's bluff in Friday's Fair City on RTÉ One and the RTÉ Player.
It's all part of the drama involving Mondo's upcoming trial over Anto's death, Hayley and James's bid to get Holly to testify against him, and Holly then blackmailing the couple with a secret recording.
In Thursday's episode, Hayley told Holly that she needed to testify against Mondo or else Hayley would tell Emma about Holly's involvement in the spiking of Greg's drink, which would see Holly kicked out of the house.
But on Friday, Holly shows once again that she is not to be underestimated.
"I never agreed to your crazy plan," she tells Hayley.
"Well, you need to agree to it - now," says Hayley.

"Do you know what? Tell Emma," replies Holly. "I survived without the Raffertys before, and I'll do it again."
Fans can find out what happens next on Friday on RTÉ One and the RTÉ Player at 7:30pm.
Fair City airs on RTÉ One and the RTÉ Player on Sundays, Tuesdays, Thursdays, and Fridays.
