Something is confusing

Hey guys in todays episode Anjali goes for jogging ...comes back suddenly and confronts AR......they convince her quite well using Niki....But as soon as Armaan left the room he speaks to himself that ab Anjali ko yakeen dilana hi padega....But anjali never said anything like she hasa suspicion or somthing of that sort.....this scene was quite contrary to the latter scene.....Wht just happened...Any ideas????
