What if this is the twist?

What if this 'Neil's biological daughter' is a plan between Neil and Juhi?

Juhi said to Neil "RP jaan ki baare main baat kar rahi thi, woh tumhari aur meri bacchi

Juhi has clearly lied, maybe to hide the fact that her child is a result of rape. If she told Neil the truth am sure he would've understood and helped, why did she have to lie??!! 😡
