For the first time Sreesanth was having to defend himself alone (simply because Salman wouldn't listen to Deepika's excuses). He obviously couldn't take criticism.
So he decides to go to the washroom with the mop and create a scene? Who knows if he really beat himself or the wall with the mop! I mean who would take the mop to beat themselves?
In the heat of moment you actually think of all this?
He cried, not denying that, but that's because he was criticised and he can't take it.
In my opinion, it was all fake, and another way of seeking attention.
