Third Person's Narrator
Somewhere in a building, he was with his binoculars, watching the house a mile away. He hoisted his binoculars to the upper windows and saw that guy chit-chatting with a little kid, who is that child? Could he be his son and the way they smiled and laughed made him assume they might father and son? Whatever the case may be, he's getting his revenge on her. He needs to avenge his parent's death and what they lost to her parents. His parent's business crumbled 'cause of them.
He watched them leave the room to God knows where before lowering his binoculars to the lower windows. Zooming in. He saw her, his target, and another male figure. From their stance, facial expressions, and from the way their mouth moved he could tell they must be in a hot dispute. He wondered who was that man too, could he be? He shook off the assumption in his head. As far as he knew she was never married.
