in the precap when he walks away i think he is angry with himself and is still blaming himself for her being in this state, so i probs walk away from her thinking that it might protect her if her stays away....or something like that
or the other thing i think is that he might be angry with sadhna for being in such a bad state... as in that if she left him then he would be all alone without his dost..... if you know what i mean....
i hope tomorrow eposode is great as todays....and cant wait for the love story track to start.... but with alekh being back to normal now..... come on rajanji make it happen....
