I watched it last week and can't see it today, but will write more about it...
Daya and Abhijeet(or rather Daya sir and Aditya sir) instantly gelled well from the Stolen Dynamite days. You can feel that they got along well from day 1. There was Jayanth before Aditya sir, but that spark was missing when you see Daya with Jayanth. A very simple dialogue - 'sir main aapko akele kaise jaane deta' to which Abhijeet replies 'tumne dekha kisi ko mujhpar nazar rakhte hue'...it was looking as if they were already working together for quite some time.
One can feel how bad Daya felt about the entire episode as he says 'woh din main kabhi nahin bhool sakta' as if he thought that he had in some way failed in saving Abhijeet from the kidnap and memory loss. Looked like he wanted Abhijeet to return back to normalcy more than anyone else.
Abhijeet is usually a strict senior. He tells Daya - 'maine mana kiya tha na, kisi ko aane se'. To which Daya very sweetly says 'main aapko akele kaise aane deta' and Abhijeet doesn't scold him for it.
They both were tooo cute - right from day 1.
