I dnt knw if i have missed something...but why does it even matter ..😛
Because naamkaran is the kaand between Dhara and Rishita and Raavi is there for the Janmashtami pooja.
So she goes to her shoot during the naamkaran and comes back by the pooja, also Raavi isn't anywhere during the naamkaran.
I thought if Raavo leaves then she might get in an accident but if she is back by Janmashtami then she is fine.
Unless off course Janmashtami pooja happens before Raavi leaves.
I lost my train of thought lol, hope I didn't confuse you.
