Oh yes! Shaheer's expressions were spot on and the director also had the boundaries clear in his mind, otherwise things would have escalated quickly towards wrong feels.The dialogue though disturbing, intended to convey that Dev is trying to take control of the situation by stalking etc ,that he can control her emotions. . By stopping her to get attached to anyone but him.Poor him, reality will strike him so bad when he realises that Sonakshi is hurt and it is her life and her decisions now and he can't control what she feels or decides about Ritwik. This will lead to breakdown.
