RM IS NOT CULPRIT for sure.......makers are not that much fool to show this name sake twist......
about Pragati Being Bani twist...like tendercoconut suggested Pragati's father found Bani three years ago....bring her home,tried to save her but failed and before dying Bani told eveything that happened to her to father daughter duo.....and Pragati came to find Bani's murderer simple......
How bani knew that the incident is not an accident but a murder if it's a car accident and breaks fail we can understand but falling from cliff is murder how anyone can concluded other people may be know about fence tempering so they can interpret but why bani jump into the conclusion in chal someone shot there car so accident happened in qyamat fl is come out if car and stuck to a tree but someone pushes her so they knew about there murder but here how bani assume that it is a murder attempt and rm I think this is the first time in ek show that ml is aware of fishy thing in his wife death but still we never saw rm in action. Most of the people thought once rm knew about the bani murder he get a reason to live and with pragati tried to figure out the culprit. But he was always shown negligent towards it.
