Even just before a "Painful" death, the CTs are not interested to give the character Sadhna a breather.
Sadhna is consistently being tortured by some of the most dispicable dreams
Infact I feel that Sadhna is angering Azraeel (Angel of Death), or as some people will call him - Yamdoot.
In many beliefs ... this will only prompt Azraeel to take Sadhna's life instead of Ragini ... because Sadhna just doesnt let anything to happen with Ragini!
Sadhna will eventually take Ragini's death for herself ... this is how I feel it is about to turn out.
The Baby, as Bani said ... is probably going to be Sadhna again (even though I feel it is unlikely).
...
Sadhna's last sacrifice ... and then she will find eternal MOKSH.
