I think Veer is a very interesting character. He is strong and self-made. He worked hard to achieve what he achieved. Krishna and Veer started off at a wrong foot.
Yes, he hated Krishna for messing up with his career he created after so much. But then when he realized that she had lost Radhay, he felt sorry for her. Yes, there was a lot of misunderstanding with the whole Batra thing and he wanted to torture her and yet he's not an evil man.
Remember that thoughtfulness he got into when his mum talked about Santosh and predicted they might end up being great friends? The when Lalia talked to Veer. He softened even more. I felt that since then all his taunts and him being all bad to her was so that she could come out of mourning and starts her struggle towards being something, again. Then Veer coming after Krishna at the party and apparently saving her and the necklace.
I personally feel the seeds of love had been planted during all these events.
Here he was probably fighting between being angry at her and liking her as a person and admiring her. He wanted to hate her, be angry at her, but he had slowly and secretly started to admire her.
When she agreed to go to London, he probably decided to stop being angry with her.
It was this trip and all the happenings that just made him fall for her. He wouldn't leave her alone at any point.
I felt when she talked about loneliness, he felt sorry for her.
The gunshot made him realize her importance to him. She had unconsciously become so important to him that he broke down. I think he loves her but has not realized yet.
The gaze and thoughts he went into when telling his mum about Krishna made me feel that he feels strongly for her. Or at least her loneliness matters to him. The smile revealed a lot too - when the mother asked if he had called her yet.
I am looking forward to Veer realizing his love. It would be interesting to watch. And Krishna falling in love. How will she struggle between Radhay and Veer? I think when she finally falls in love and declares her love (or maybe not), will the Radhay accident be revealed. And how she accepts that truth and tortures Veer and later forgives him (obviously) would be an interesting watch.
And amongst this love story would lie convincing the Shuklas and how each character plays their part in uniting and separating Veer and Krishna.
Makes me wonder if KCL is actually ending soon? They can't cover all of this before IPL (starting 24 March???) Of course, there is this story of chutki that still needs to be developed. Oh damn - I forgot the pregnancy test results... Yeah that will also make a very interesting track - if written well since the actors are amazing!
