She held it in her hand for a second, then looked back out at the crowd.

When I looked back a bit later, she was gone.

He knew she was looking back the way they'd come.

I turned away from her and looked back out at the river.

She ran across the street and out of his life without looking back a second time.

Then he looked back a second time, to see if she was still there.

He turned and walked away a few steps, looking back the way they had come.

It was only on looking back that I came to understand.

She made no response, simply looked back out at space.
