Anna squares up to Pete in Friday's Fair City on RTÉ One and the RTÉ Player.
In Thursday's episode, Pete threatened to expose that Anna practised without a nursing licence if she told Carol about the mix-up with her cancer tests at the medical centre.
Now, sick of Pete's manipulation, Anna threatens to reveal the truth in front of everyone in McCoy's.
"I don't think it's better if we 'keep things quiet'," she says. "I think it's better if I shout it out right here, right now."
Fans can watch 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.
