He looked up at me, and a smile flashed over his face.

He seemed to think about it for a second, then flashed me another smile.

The smile flashed bright and I think real for a moment.

The smile flashed like lightning and changed her whole face.

A smile flashed across her face, a moment of brilliance.

His smile flashed, but there was no amusement in it.

His smile flashed, sending a wave of heat through her.

He paused, and a grim smile flashed across his face.

The smile she flashed him was almost wicked with delight.

Gwen was still a moment, then flashed Rod a smile.
