Humeira was completely heart broken after Ayaan claimed he wasn't in love with her. And after meeting up with her accident, she adopted another personality – Rajni Shukla. Maybe it was her unconscious way of dealing with the reality and wanting to forget about Ayaan's rejection that time or maybe deep down inside, Rajni Shukla was a hidden part of Humeira. So she became Rajni Shukla, who apparently had a very loving husband called Vikram. Humeira's wish has always been simple. She wanted to be accepted and loved so it makes sense that she would become Rajni Shukla.
With Ayaan revealing the truth to Humeira about Vikram, what will happen to her now? Also if Humeira does return, will she remember Rajni or her moments with Ayaan? And more importantly, how will Ayaan react to her now?
Personally, I'd like to see Humeira trying to reject Ayaan this time and Ayaan having to go that extra step to make her fall in love with him again.
