troubled look

The troubled look that flooded her face told him it was the wrong question.

She saw the troubled look in his eyes before he hid it behind a smile.

He saw the troubled look on her face and asked, "Does it mean so much to you?"

And the third time his face took on a troubled look.

He came over to them with a troubled look on his lined face.

A troubled look passed across his face, like a shadow running.

I glanced away from the troubled look in his eyes.

Then he stopped, and a troubled look came into his eyes.

She understood now the reason for the troubled look on his face.

I could tell by the troubled look on your face.
