After the defeat, Vikramaditya's temperament didn't improve, causing him to physically abuse a respected chieftain at the court. This led to nobles placing Vikramaditya under palace arrest, leaving Udai as heir-elect to the throne. The court appointed a distant cousin of the family, Banvir, to act as regent. He was supposedly the illegitimate son of Udai's uncle, Prithviraj. Banvir considered himself the legitimate heir to the throne, and assassinated the imprisoned Vikramaditya. He subsequently attempted doing the same to Udai, however Panna was alerted of the situation and sent Udai out to a river, while setting her own son, Chandan, in his place. Banvir came soon after, asking for Udai. Panna pointed at the bed, now occupied by her son, and watched as he was murdered. Banvir arranged a meeting of the court and informed the chiefs that both the heirs were deceased. He then claimed his right to the throne and appointed himself king of Mewar. Panna and Udai fled to Kumbhalgarh, where a governor agreed to grant Udai protection.
