My guess on the precap
Till Pre agrees for a search in SN, it is real (though i don't have an answer to how Anu was released). And Sonalika will dream of all those scenes shown in SN and by the time she is back to reality & they get ready to go to SN, Moloy will appear and stop it. Either Pre has informed him of Komolika and they both are trapping Komo & bag is safe with him; if not he will say that he trust the Sharmas and is taking back the complaint (by this way he will be redeemed for what he did to Pre). Hearing this, Komo might create a scene, after which she might go out to see the person whom she had arranged to put the bag in SN, after which Veena sunaofies Mohini. Sona gets the engagement photographs from the person she has arranged, which is the ones that will fall in front of Anu. And there the drama begins.
Irony is that Mohini called the police to arrest Pre and destiny plays out that her dear son directly gets arrested by the police. Mohini....your count down has started. And i am like anything.
