I just wanna say If Avdesh dies it's because he is saving Pihu from bhootni and he takes the bullet. Pihu by then, off course knows Avdesh is innocent - Bhootni is the one and only enemy.
But I still think at the very last, Pihu will turn around and say she is Arpi. She used Dev 'killing' as an excuse to infilterate the haveli to be nearer to see what Bhootni is up to!...this goes back to my theory of CVs playing it safe, one moment she is Arpi and next she is pihu. There is no denying in the earlier scenes, she often had these looks - when she first see's Avi in the market, there was tears in her eyes...then that look of anger when she was rushed away from the mandir, Avi lying on the ground watching her and she looking back - boy oh boy she was angry...then when bhootni came to meet 'Pihu', she knelt down to pick the glasses up, she was challenging Bhootni silently...no two ways about it!! ...The final bit was when Avi leaves after covering her up with her dupatta, that look on her face...!!
But now they are playing it the other way, she is totally Pihu...so wait till the last moment (if I lose hope now...π‘π€’)...
er..my two cents.ππ³π
