There will be small misunderstanding / argument between AarYa due to divorce thing and Prashant truth hidden from Yash and Scindia. But knowing that Yash and Aarti are in deep love now...that should not create problems.
IMP thing is ... Prashant is regretting what he have done with Aarti ...he realized his mistakes when he faced same thing when his current wife left him. Now the thing is that they are showing Prashant is repenting for his deeds.
Prashant must have accepted that Aarti is now married to someone else and from her condition he realized that she is loving Yash. Prashant now trying to bond with Ansh and surely in future he will try to get Ansh ... He will try to convince Aarti to handover Ansh to him and also will go to the court to get Ansh's custody...
This is the future track..when Aarti along with Yash and Scindia family support fighting with Prashant for Ansh.
