Yes Di the last scene of prishna really showed Pintu's concern not only for his Brother Babloo but for his krishna as well . He knows once pinky comes to know abt their plan , she can do anything drastic to them . He doesn't care abt himself but he do care for Krishna . And so that concern that worry was very natural like a typical True Husband who loves his wife more then himself .
Yes it's an open war and it gonna be very very exciting to see it . I am waiting to see how Prishna will save themselves from Pinky's eyes when Krishna will be doing preparations of IAS. As far as Precap is concerned I also think that it might be an innocent mistake by krishna like taahir said but U can't say , Pinky can do anything . So Will comment about that after watching the episode ,
