it is tom

Mona's POV:

And in the corner of the room, I find many broken sticks and by looking at the sticks it is clear that Tom used all those sticks to beat him. And I looked at Williams eyes and his eyes are opened semiconscious and bearly looking at me.

Meanwhile, Tom came close to me and gave me another wooden stick as a hint to beat Williams. 

Tom: You can take revenge on him...

I nodded my head as ok and slowly went close to Williams and when I am walking close to him I am getting the flashes of last night incident and how he takes advantage of me and how crualy he behaved with me. I immediately take a long breath and slap him on his face with all my force as a punishment for his cruel acts. He looked at me with his smirk smiling face. I did not accepted his reaction I think at least by now he realises his mistake, but he didn't...

How can he still looking at me in such a Smirk way?
