That did surprise me when he offered friendship but when i thought about it, its makes sense, coz one he is a doctor, and he has just seen Anjali in hysterics calling him Kkavya over and over again - so as a doctor he had to make a step forward and also like he says he doesnt offer friendship to anybody and once he does he will stand by them, like he does with Reeva, but sometimes is rude and hurtful to her coz of some the things he says to her.
I agree wid u yaar๐
