Thoughts on promo

I know almost everyone in here has posted there thoughts about the promo so have but this one just crossed my mind based on the previous promo history how they played out and from kethki's update on insta as Avni is still not arrested and different clothes
we know VR killed juhi and Neil witnessed
But what if they just take avni under custody just for interrogation and Neil does help stating juhi instigated avni and to save mishti avni shot juhi I mean it can be a valid argument.
But Neil is really angry on avni for doing this decides to break her marriage since avni broken her promise
