Aahil is very basic I find, all he wants is someone to take ownership of him. Someone who demands that he BELONGS to them. Like Tanveer does that. Sanam doesn't get that all he wants is some good old fashioned "haak zatanah" and he will be putty in her hands. Arnav was like this too. Though, Arnav was better developed. Aahil is their mid-way soap invention, so they didn't give enough depth to the character. All he has is child abuse. He needs more.
KV would have done so much with more depth, really wish he had the whole show so that the CVs would take time to etch out the character. Anyways, he is still doing a lot on his own. Today, in the shooting video I saw how he discouraged the director from making the jealousy so abusive. It is true that 4Lions often shows abuse to mean passion, it is a thin line. I am glad an actor had the sensitivity to see that it is not right. He balanced well on that line. The CVs weren't doing their job of balancing so well. So he is adding depth where he can. Very impressed. 👏
