There are so many theories going on in my mind regarding the person who abused Maya. Things would have been so much easier for speculations if Rudra wasn't wearing that bracelet!
Theory 1:
Simple. Khandaani bracelet. MJ's the villain. Mrs. Roy now dislikes MJ, hence passed on the khaandani bracelet to her grandson
Theory 2:
MJ had a brother, a womaniser who trapped Maya in his love! MJ also fell for Maya. Later when Maya got to know of brother's truth, he humialated and abused her. MJ knew of everything but he kept quite and took the blame on himself because 'family's izzat' lol 😂 So rudra can wear his uncle's bracelet
Theory 3:
Something related to Antara and Diya. I feel these two are very fishy.
