Shubha, she might know that Shyam is after ASR's property but still she is not able to convince hm to wait at the airport and he gets kidnapped. She somehow is not able to stop it. Anyway they need that track to cover for Barun's absence.
As for me both the characters were manipulated, Arnav with his last dialogue of her being a gold digger and Khushi going to Shyam for help. Only Shyam was in character. Also this IPK Cvs we are talking about till now except the terrace confrontation, no loop has been closed and they are simply giving the villain upper hand right now like any other saas-bahu serial and it will be sometime before his cover will be blown.
I hope they stayed true to the characters also the TRPs audience will not be able to read too much into all these hidden messages. They are all ordinary people who just want to watch a good show after a long hard day.
Khushi not knowing to read English or pretending is still puzzling. She could read the Payal-Akash fake divorce papers that Arnav sent her.
