I avoid using such harsh words, but after watching the promo, must say Sid is pathetic n a sadist.
Like I had mentioned before FD isn't an abuse, it was used metaphorically. Now i don't know if in Sid's circle they use it in some bad way or is even otherwise used in a bad way? Like maal when called for a person, especially females, is considered bad. But have never come across FD being used in a bouble meaning way, but Sid made a big issue that it has been used in a bad way. Arti seems totally unaware, but it was Sid who drilled this into her mind. Sid should have shown some concern if he truly cared for Arti as it seems to have led to another anxiety attack for Arti. What friends like Sid who needs enemies. Instead of calming her down he made the whole FD thing into such a big deal that it led to arti's anxiety attack.
PS: made this post based on promo and from promo it seemed Sid was the one to blow the whole FD thing out of proportion. If that isn't the case in the episode, i will delete this post.
