Why Rohan?

Can someone explain to me why Bharka is suspecting Rohan? What did he do to make her think he is working with Radhika?

Barkha thinks that because she had kidnapped him so he is trying get even with her.

Actually she thinks she is overintelligent yaar.
You should have seen that scene how she made all way out of suspection except rohan.
virat-if he would have mind then he would have become RP already
BB-she is so scared of radhika/kanha as bhoot.
daima-no voice.
padma- she is so kind to her.
MOHINI-she has no mind.(it was hilarious in hindi actually if u understand -"mohini ki to khud ki akal ke lale pade hain")

so she made all way out and was on the way of suspecting rohan and then after talking to him,she again overconfident ,yes its rohan only,yes.

maha murkh girl ,no no,no girl(its insult to girl word) its demon only.
