The Nest viewers gobsmacked by explosive 'baby daddy' bombshell

The Nest viewers were left gobsmacked this evening by a bombshell revelation at the end of tonight's episode.

Tonight, Jack found out about Kaya's past, leading him to confront her at prom and run off.

Dan, played by Martin Compston, and wife Emily (Sophie Rundle desperately tried to find her as she went missing.

Eventually, Jack managed to find Kaya (Mirren Mack) as she lay collapsed and phoned for an ambulance.

She was rushed to hospital, where she was forced to deliver her baby early.

Thankfully, the baby was delivered safely, however a revelation elsewhere left viewers dumbfounded.

Her social worker spoke on the phone and confirmed that she had been in a sexual relationship with Kian, who was found dead, 25 weeks ago.

The baby also happened to be 25 weeks when it was delivered - meaning that Dan and Lisa may not be the baby's biological parents.
