Why i think so is because:
All her weird expressions like when she was listening to arzoo and nausheen's conversation and when ka was talking about broken pot, etc.
When she said, "shayad usko kisi ne chat she dhakka maara hai" and she's so sure and everything she guesses is so detailed.
There's just somethin wrong with her, its easy to tell
That's all i could think of for now... 😕
