Vaastav style ending

I would like to see a Vaastav style ending where Dadi herself exposes and punishes Ragini (not by shooting her but possibly sending her to jail or an asylum). In the past Dadi was quite angry with her when she felt she was crossing over to the dark side. We've had enough hints throughout that Dadi is only siding with her now because she thinks Ragini is innocent.

Though Dadi doesn't know how evil Ragini is, I think she will support her even when her true colors come out. Remember Dadi trying to kill Sharmishta as part of the puja? What was Sharmistha's fault - trying to marry to Shekhar, right? Swara is accused of snatching Ragini's love, which is a bigger crime. Even if her laado's crimes are exposed, Dadi will continue to support Ragini. After all, Ragini is Dadi's next avatar.
