1) Probably Tanveer spiked both Asad's and Zoya's drinks (if they had, lol) and they both got intoxicated and stuff, and unable to control themselves, and they started dancin together in front of everyone. Sort of like the bhaang night except everyone is there, lol.
2) Probally this is Asad's gift to Zoya!
**As a scenario** The party was over, and as people were exiting the room, Asad caught Zoya's hand and pulled her towards him, wrapping his other arm around her small waist. "What's wrong with you Mr. Khan! Everyone is leaving, let me go..." stammered Zoya. Asad didn't pay heed to her. He simply put his finger on her lips and brought his face closer to hers. "But Ms. Farooqui, this night isn't over yet. Didn't you ask me to give you a wedding gift?"Zoya's lips formed a small smile as she remembered that exact night when she asked Asad for a gift. So you remembered, Mr. Khan...
Cheesy...I kno...Thank god I don't write OS's and FF's
3) It's a dream! After all, it does look a bit dreamy...Too good to be true?
