3 more mirror symbolisms were shown by Director Wasim Sabir in Today's episode.
I have added them in the my post. Those were:8. When NA was talking to Anjali about the party and about making Astha just like her. When NA says"Aatha mein apki Chavi dekhna chahta hoon", Anjali was shown mirror and NA was not. So, that means Anjali does not like Astha to become like her, she is just doing this for NA's sake. And NA has this image of Anjali but she is different from inside.9.When Anjali was talking to Sojal, Anjali's image was shown in mirror - that is obvious as Sojal does not know what is the truth of Anjali. She only is aware of this image/face value of her MIL.10. When Shlok calls Astha and reminds her to be on time, his image is shown in the window glass which is interesting.Thanks to@ Lachii for adding the pics to the previous ones which I have added too to the post, and one more from @OQ.
