Pri,
1) Tej leaving behind the black book, did not sit well my logical mind.Remember, how protective he was abt that diary? He would not let Mala touch it.. And kept it with him or in a safe place.Tej came back to the haveli, took money jewels and mala but left behind the evidence of his crime?My justification is Tej was under lots of stress, anxiety and in a hurry to flee that he completely forgot about this ..2) paro reaching the temple, my justification, Rudra told that army haveldar, to get whatever Paro needs, just keep her away from his room.. So i think she took help from him to go to the temple.
