If they want to show a Naren-Ankita reunion, it will be Naren.
Ranvijay doesn't even know what's going on so unless he happens to get out of the coma and save her by accident, there's no way he would save her
I would love for Ankita herself to run away. This would show that she's independent and doesn't need Naren's support to make it out.
Shashank would be great too, but since he isn't a lead, they probably won't let it be him.
