Neighbours to air a rare flashback in Chelsea Murphy baby story

 What really happened at the airport?

Neighbours is set to air a rare flashback scene in Chelsea Murphy's baby storyline.

Viewers will remember that Chelsea made a surprise return to the soap in a cameo appearance during the end-of-year finale episode in December.

Chelsea's sister Cara thought she spotted her sister at the airport. After catching a glimpse of her, Cara brushed the possibility to the side, convincing herself it wasn't Chelsea.

Later in the episode, it was confirmed that Chelsea, who last appeared on the soap back in May, was back in Melbourne and she was seen at the airport sporting a baby bump.

Next week's episodes see Cara and Remi return to Ramsay Street from their holiday in New York and we see what happened at the airport in full for the first time.

In scenes which will air on Thursday, February 6, Cara returns to Erinsborough from New York but she's carrying a huge secret.

Nicolette notices that Cara is dodging meetings with Paul and that she has been asking leading questions of Andrew.

But when Nicolette overhears a call between Cara and her mum, she realises the shocking truth – that Cara has seen Chelsea.

Opening up to Nicolette, Cara tells her about their encounter at the airport, which is shown in a flashback.

In the flashback, viewers find out that Cara did see Chelsea face-to-face at the airport. Chelsea was heavily pregnant and in need of help, but a shocked Cara rejected her.

Weeks after the encounter, Cara is still full of regret with how she handled the situation knowing that Chelsea must be somewhere all alone with her newborn baby.

A supportive Nicolette vows to keep Cara's story secret, saying she will help her to track down Chelsea no matter what it takes.
