Aarzoo ko Zaki ke saath dekh kar mujhe takleef ho rahi hai... Aarzoo ke bare main itna kyon soch raha hoon? Is baichaini ka matlab kya hai?
First let us get this thing out of the way.
Sahir and Aarzoo are soul mates. For some people, "the point of no return" begins at the very moment their souls become aware of each other's' existence. The story started long before they met. Lovers don't finally meet somewhere. They're in each other all along. Dard hi dard ko kheenchta hai... The qaynaat wants them together because they were made for each other.
Now what are these emotions of Sahir? Is it jealousy? No it's not exactly jealousy. It is takleef which is kind of aberration from his normal cold self. He is feeling something different and has started thinking a lot about her. Why?
Because Aarzoo does to him what no one else has ever done to him. She questions him, argues with him, isn't scared of him, at times goes against him. He has never seen a girl like her. At times He is amazed by her innocence. She looks angelic at times, she reminds him of his past. This has a potent charm of its own. He is surrounded by people used to his authority bordering on sycophancy but she is like a breath of fresh air for him. She manages to make him pause, take notice; it's her simplicity and zest for life that attracts him. He has been in this condition for some time, he must be feeling suffocated, she liberates him...
Pyaar kiya nahin jaata hai ho jaata hai...
1. She made him give up his window seat.
2. She threw a phone at him
3. The sight of her choking in the Glass case... made him lose control publically.
4. She was angelic in the pool, a symbol of innocence.
5. She snatched the burnt toast. She dares him like no one else can.
6. She questioned his decision about Linda's leave.
7. Aarzoo gave him missed calls.
8. She made him smile.
9. She praised him according to Alvira.
10. She put a paan and Baigan thingy on his head.
So yes, she evokes emotions in him that are foreign to him. It is curiosity, anticipation, confusion, meetha meetha ehsaas, ... Different stages of love...
Sahir hai to ultimately insaan hi, on top of that he is a poet. These feelings have always been there. Now the latent emotions are coming to the fore. He had programmed himself to be a Robot. But uski seene main bhi Dil hai. He will fight these emotions but still feel them because uska Chaand to Aarzoo hi hai... He is a lover... Sadiyon se apni mehbooba ka intezaar kar raha tha... Ab jab mil gayi hai to yeh feelings to generate hongi hi.
When AYM fall they fall hard and after that there is no turning back.
What is meant to be will always find a way. This is destiny. Sometimes a moment changes everything.
But I think the real reason is the Imarti. It had the Love potion in it. So the problem is solved. The real culprit here is the Imarti.
