I don't think you can locate Bhadra. I never found anything else related to her if you choose the Amita storyline.
In fact it's strongly implied that Amita killed her (or more likely had her killed) so that she could never be used by anyone supporting Sabal's agenda of ancient tradition. I have to be honest and say this part upset me more than any other part of the game... and in fact more than probably ANY game. I did many bad things to Amita's body for what she had done
Also I find it very weird because in the earliest parts of the game (the first wolfs den mission and the first attack by Paul's men on the village) it appears that Amita cares for Bhadra and is protective of her. Later to find that she simply didn't want Sabal using her as a symbol to unite the people feels... wrong). It's intentionally ambiguous though so maybe I read too much malice in her words and maybe she really did actually send Bhadra somewhere safe. Maybe.... I hope so.)
