I was close enough to watch her eyes, and see the flicker.

And once again thought she saw a flicker of movement.

She didn't answer, but he saw the flicker of fear in her eyes.

He saw a flicker of light from above now, pulled further back against the wall.

Without seeing even a flicker of movement, he was before me.

He saw the flicker of fear in her eyes, and decided to press it.

She looked into his eyes and saw a flicker of something like hurt.

Suddenly, he saw a flicker of yellow light up ahead.

He looked right at me, and I saw the flicker of his recognition.

I'd seen a flicker of interest in his eyes, but no recognition.
