You have combined vanvaas and sisters track. 😆
Vanvaas track will about brothers their families only. Shivaay should only go because he is the one most attached to family. So he leaving only makes it dramatic. Om toh hamesha jaane ke liye ready rehta tha.😆 Uske jaane se kya drama hai.
And in vanvaas track couple should be supporting each other. Not going other way. 😆
Yeah, I got confused.😆 That was for sisters' track.
re: Shivaay's illegitimacy
If writers do plan to make him a mistress's son, then maybe it was planned as a punishment for Shivaay's arrogance in the initial episodes. Karma. Just because he's the ML and he is now a better person, doesn't mean he can escape the consequences.
But yeah, I don't want Shivaay to be an illegitimate son. That'll kill the SSO in him.
