It was an okay episode. I had expected a stronger reaction from Rahul. And it still doesn't change anything, because yeah, Kakun'll get rid of Aman maybe - but Rahul is still married to Naina, and he won't leave her. That's what I said before, too. That if it ever comes to choosing between Kakun and Naina, he will choose Naina out of responsibility and maybe some feelings as well.
Kakun is probably pregnant with Aman's child, too.There are a lot of things that they can't make better in two episodes. The leap is supposed to happen in the 100th episode.
