It shouldn't have been news to Raghav if a girl, you have bullied, has joined hands with another girl ,she must have deemed as another victim of his viciousness, to deliver justice at his door. But it became a big deal as the whole fiasco reeked of betrayal to him.
He didn't went after that girl in the picture because it was vengeance from her side and he took it exactly as it was, base idiocy at best and pure malice at worst. And he didn't expected any better from her.
But from where I see he invested more trust in Pallavi than his better judgment should've allowed him. It wasn't just the scandal.
Finding himself in the same situation ( at the verge of loosing his mother just because he again decided to trust a girl) brought the worst in him.
And he had no one to blame except himself cause he must have known better this time. And in a sorry attempt to rectify his mistake for cutting pallavi a slack he went after her like a raging bull.
I'll just say that when blinded by anger people tend to loose reason and Raghav had equal right to be angry in that situation as anybody else, if not more.
This post doesn't mean that what he did should be easily forgotten I want him to grovel real hard once he comes back to his senses.
