If you guys remember when Razia heard the news of the shooting on TV, there was no surprise on her face, she simply took it off. No interest to find out how it happened etc, I had a feeling from there that she was not surprised because she knows about the shooting. Also this happened right after a phone call between Dilshaad and Rashid where Dilshad was telling him that she found out something. He repeated it out, perhaps Razia, hiding like her sneaky self, heard and that was what prompted the shoooting.
