her anger towards raj i think its practical
i can understand tht she's mad at him because she worships him and perhaps loves him too and gettin to know he killed her bro doesnt make snese to her when he he cud have found another way like finding the real culprit.... so her anger is justiifed ( anyone wud react in same way) so its better she finds out the whole truth before doin anything else silly like shooting him as she did earlier n see n realize htt he didnt have to tell tht part but still did risking his career becuase she's imp for him n he trusts her n so maybe he's tellint hr truth ...n y on earth wud her bro tell her in mail to meet raj if he didnt trust him.
