I have noticed that Tulsi is not physically present in any scene with other actors, especially in the scenes with Laksh, KT and mihir. I think they have shot Tulsi talking, but shown her double in the scenes when they show her back. I think we can know this because her necklace seems to be missing everytime they show her back.
I find this kind of annoying because it dampens the intensity of the acting. Especially in the scenes between Mihir and Tulsi. If you can't physically see the opposite actors's emotions, how they are performing, then you can't feed off it. I find Mihir and Tulsi scene so mundane and so lacking intensity, because they are not performing together. Mihir always looks preplexed, and he doesn't show varying emotions on his face. He looks and acts the same way in every scene. I wish he always didn't look so confused.
