I thinkom is suyash. I think om didnt pass away, like that woman said he came back to life. i think suyash died in the hosptial around the same time as om in the hosptial, for some reason like trishna hiring them to do surgery on om and turn him into suyash. I think that the person who died was suyash, with om's face. the person who is alive now is om with suyash's face. I think the hired doctors did plastic surgery on om and suaysh and switched their faces. if you guys remeber suyash never talks about his past and they talk about a " tragedy". but they never say what it was. maybe the mother doesnt want to admit that her son is dead so she keeps on believing thats suyash or maybe she doesnt know. Suyash / om doesnt remeber becuz he lost his memory. I dont kkow but its a hunch.
wht do u guys think?š³
