After all those physical and mental tortures, Riddhima still failed Vansh and Angre's plan and even back in house and blamed Aryan and still fighting against everyone including Vansh and his family members whatever reasons are. I did not seen any others characters of this show this much strong till now though they always give very big big dialogues to almost everyone. That's why I find Riddhima's character is the strongest character of the show if I compare it with others characters of the show.
Every character has ups n downs.....n diluted along the course.
If Riddhima's character is written as weak then how will story progress??!!!
