I think Armaan will come back and explain that he loves Ridz too much and for his sake and her sake she should marry Sid and that Sid will keep her happy and she will have a normal life with him at least. And then sadly he will slowly walk out again.
But this track won't work. Sidma marriage track won't be accepted. Everyone will still long for AR. Sooooo a simple solution would then be AR getting married, in the following 3 episodes and then leave for U.S. or whatever 😊
Then they can continue with the new interns and bring a new girl in for sid. And perhaps a new couple duo
