From the precap it looks like Yash is going to find out about Prashant.(the precaps can be misleading sometimes). If he does, Aarti deserves everything she will be dealt with.
I am sorry. I love Aarti's character, but today I was feeling really sad for Yash. If she wanted to call she could have made the effort to call Yash. He deserved at least the phone call to let him know she was OK.
