Divya is definitely alive - also Pia needs no help she is very strong herself & has devik powers in her which will not only help Pia in protecting herself but Ansh also ...
I think because of that devik symbol on her body the Dayan will not be able to touch her or use her powers on Pia ...
Infact Pia will act as a shield and protect Ansh from both the dayans ...
I agree. That's why Mohena locked her in the room. They can't harm her or touch her bodily!
