according to history Salim was close to his mother MUZ and respected Salima-Ruqaiyya..and was a darling of his Dadijaan Hamida Banu.
I personally dont think there will be any tiff between JJ coz of Salim..but the way story is going Salim will be against his parents and closer to Ruqaiyya.I agree till JJ stand as one, I dont care much...still the kid Salim getting influenced by evil Ruqaiyya makes me feel sad for him..I adore Salim way too much.
