After reading all your scenario's I have got one in my mind which would strenghen Michi's bond.
Prachi after knowing that Neev is negative ,she will kill Neev ,but Milind would be there just in time .After Killing Neev Prachi will faint,so Milind will take the blame and go to jail.Prachi Will come to know about Milind's sacrifice and will go and rescue him and go to jail,Milind being the best pati will save Prachi with the help of Ranvir and ranvir helps him with his own selfish motives.This is one scenario.
There is another scenario,assuming Neev is not negative and will die saving Milind.Meanwhile Soumya and Ranvir will hook up and Soumya is pregnant with ranvir's child.But actually Ranvir is negative and is after milind's life ,so prachi kills Ranvir and she does not know about soumya's Pregnancy.But Milsi comes to know about her and Ranvir and takes the responsibility of Soumaya's child and intern proclaim that the child is his(MIB-Milind is Baap track).This will be a test to Prachi's trust on Milind .Will she support him or doubt him will be the question .The second track is from a telugu movie (Chinna rayudu).I don't know if anybody have watched this or not.
Please tell me your comments.
