Is she jealous

I felt rani was bothered with kiara and veer proximity

Poor girl she gonna fall first and her suffering will be more

As for veer i think rani will do something to him and his family member wich will impress him

And than something horrible happen to her

In that moment his feeling for her will be developped

It is just pulling of heart strings (as she said Patang ki Manjha - Kite strings getting strained when the kite flies high)

Yup, it's not jealousy . It's just a feeling . She in her subconscious mind considers him as her husband . This started to happen after her marriage . I think she doesn't like , her husband to be with another woman. It's natural . She never felt before her marriage .

during Kiara poison scene - Veer took time to say to Kiara we can be friends, it was Rani who had sigh of relief when he said yes for friends

She is a bit fidgety was because the servant watched over, secondly Veer used to talk to her either she used to start or sometimes he too used start the conversation

Loved the ointment applying scene

But now they are at logger heads it is she who starts and they end up at each ones throat

So she feels left out now, As Vikram has maintained distance, Pinku not there, so she is fidgety too but being filmy she went to the "pulling heart string" conclusion
