Will Paro have to face some wrath on acvount of loosing her husband ? Will the villagers try to give her Sati, and that's why Rudra takes her away after she faints ? Then when she regains consciousness she thinks Rudra is evil and tries to escape from him. That is when Rudra runs after her in the desert, catches her, and ties her hands to the jeep to make sure she doesnt run awsy again.
So here he is the rakshak.
Later something forces him to interrogate her, as the BSD officer that he is. As a part of being in the BSD he is ruthless, but his soft corner for the fairer sex is defonitely showing !!!
