Madhu, has got to learn to trust RK, now they are close, she should have confided her fear to him and he would have set her mind at rest when she was feeding him when he was asking her.
Because now I agree with you Suk, RK will say, Biwi Biwi Biwi, when I say don't leave the house you should do as I tell you, had you stayed at home none of this would have happened, perhaps he will tell her when they are alone after the whole mess is over, or immediately when he sees her. Had she not gone to Chawl to dig up the gun, no evidence of her involvement, in the attacks.
