Here is a thought. Since A is vowing to find out the truth behind the marriage it means pregnancy will be revealed. I believe A told P that he will never forgive her for letting bajaj touch her like that. P is doing all this fake things in front of A. That will fuel him more and make him believe she really did cheat on him. He will then confess to her if he really did plan the accident or not hence bajaj innocence will be proven and P trust will be broken. All this might take place while bajaj is in jail. Bajaj doesn't want court, hearing etc he wants to leave there innocent.
All due to her. She is such a good faker that anyone will believe her fakeness. I don’t understand why she don’t even tell the truth already.
