At the end of next week, Ronnie finally comes to her senses as she realises the enormity of her decision to switch Kat Moon's newborn son Tommy with her dead child James at New Year. Deciding to put things right, she bids Tommy a final farewell before heading into The Vic with the intention of ending Kat and Alfie's turmoil.
Ronnie's life-changing decision comes after her brother-in-law Max Branning and his daughter Abi are involved in a car crash on Tanya's wedding day, which brings the troubled character to the same hospital where she gave birth to James in December.
Speaking of the baby swap climax, Womack told Inside Soap: "The pressure of what Ronnie has done has been building and building for months and it's becoming enormous.
"There have been several moments where she's realised what she has to do, and being in the church for Tanya's wedding and around Kat and Alfie is particularly difficult for Ronnie. But it's the car accident involving Max and Abi that makes everything just too much to bear."
The actress noted that returning to the place of James's birth reminds Ronnie that his arrival was "the happiest day of her life" and prompts her to do the right thing at last.
Discussing how Ronnie tells husband Jack the truth, Womack said: "She blurts out that James isn't his son, but Jack doesn't believe her and thinks that her depression is making her say it. He's really worried and insists on returning to Albert Square with her, but Ronnie drives off without him.
"All she wants to do now is the right thing. And after telling Tommy that she loves him as her own, Ronnie walks into The Vic to bring an end to the torment and confusion she's caused."
Womack will leave EastEnders later this year. Although reports have suggested that Ronnie will spend time in jail after handing herself into the police, her final fate currently remains unknown.
