I think the writers did a good job yesterday with Katha's apology. I don't see it as some instant realization, they had been chipping away slowly for the past couple of episodes at her stubbornness and irrational fear, and Viaan's accident hoax was that final push. Especially the conversation with Raghav that proved to be the biggest catalyst. The flashbacks of Viaan's previous accidents and her reactions to them were a nice touch to show how her pyaar started with parvaah and no matter whom she marries she won't be able to suppress that parvaah.
I remember saying that instead of mentally fortifying Aarav, she was allowing the doctor to be used as a crutch. Calling him everytime Aarav got angry, allowing him so much control over your kid wasn't sensible at all. I liked how they addressed this issue my making her acknowledge that she was making him a coward who runs away from problems in a foolish hope to protect him from all the hurt. Which is an impossible task in itself. There is no life without hurt or pain, grief, sadness or betrayal, and no parent can protect their children from them. Der se hi sahi they made her realize that.
If Aarav was her weakness, Viaan was her strength. It's as simple as that. She suffered so much because she cut off her only source of strength, her pillar of support. Uski zindagi mein agar kuch sahi hai to woh Viaan ka pyaar hi hai. It was a hard earned lesson, so hopefully she'll remember it always. Jab tak woh aur Viaan saath hain woh kisi bhi problem se lad sakte hain.

Waise for this whole month what is Sony going to telecast at 7pm slot??They could have continued the show till Dec.last and come up with new show next year.

So,wish the writers didn't come up with the horrible idea of leap which followed some disastrous tracks.Wish they have showed Kaviaan married and then their post marraige tracks.
