Even I have this doubt. Chandrachur is alive, so Anirudh will be released but Tapur is scared to give her confession. For remaining crimes also, witnesses and evidences are required. If his aide reveals all the facts, then only chances are there to get him punished
I think CC will be revealed as alive and Ani will be freed, uske baad Bon will get CC arrested under a few charges like attempt to kidnap and falsifying death... Then ek ek karke all his crimes will be revealed, leading all the way to the poison and the blast...
