Who was the man whose eyes stared so intently into his own?

He looked up and she was staring intently into his eyes.

He looked away, and into the eyes of someone staring intently at him.

She stared at him intently, and her eyes lost their focus for a second.

He stared intently at the book in front of him.

She stared intently for minutes but saw nothing moving among them.

And I could see she was staring at me intently.

He stared intently for a moment and turned to his mother.

He was staring intently at something beyond their field of view.

He was staring intently at the side of the road.
