So it's conform he is suraj not Raghav

They said- Aise chhote chhote hadse to hote rahenge warna chakor ko kaise pata chalega ki ye udka Suraj hai. Jab tak Aap Suraj ke humshakal hai tab tak jitna hate karna hai kar lijiye jab chakor ko pata chalega ki aap Raghav nahi Suraj hai to kya hoga ye bhi soch lijiye.

So it's clear he is Suraj.

Why Suraj is faking his identity

it will be obviously much more fun if raghav turns out to be suraj. i still have vibes he is suraj only.

if no memory loss, than maybe they can show some other reason why he is doing this

i know my thoughts are far fetched at times, but what if they show, that after bomb blast suraj has some tests and doc say he has a serious disease and needs to be treated after going abroad. suraj needs money but he doesnt want to come back in front of chakor bec he knows she is slowly making peace with his death, and since his treatment has a low ratio of success, he decides he will get the money off her by faking to be raghav, go abroad and if he survive, he can then come back to her and tell her all. otherwise he doesnt want her to know he is suraj bec he doesnt want to see her suffer seeing him suffering. rem how raghav said he wants to go dubai after 1 month

later they can show imli or someone else paid doc for faking his report and he isnt ill afterall.

i know they wont use it, but if they show is this way then suraj pov will be justified to hide from chakor

But so far no direct hint in show about it.
