The character of Ronnie left the soap in 2011, imprisoned after swapping her son James – victim to cot death – for Kat and Alfie’s healthy new born son Tommy.
It was announced last month that actress Samantha Womack is to reprise the role in a storyline that sees Ronnie released from prison and return to Walford determined to turn her life around.
In the time Ronnie has been away, the Moon’s marriage has broken down and now her sister Roxy is living with Alfie after the pair began a relationship. They will become engaged in a forthcoming storyline.
A source told the paper: “Alfie finds out that Ronnie is heading back to the square and he’s furious. He can’t believe after everything she’s done that she’s going to come back.
“Alfie then tells Roxy he can’t be with her, let alone marry her. Roxy is devastated but she has to be there for her sister.”
The storyline leads to Alfie growing closer to estranged wife Kat (Jessie Wallace) – the pair broke up after Kat cheated on Alfie with slimy Derek Branning (Jamie Foreman).
“Kat’s in pieces about it all too and when they thought their son had died it was one of the darkest times in their lives, so naturally they turn to each other again for support.”
