She was trying to study his face in the dark.
She didn't answer immediately, but turned her head to study his face.
She studied the face the rest of him was still behind the door.
Then she studied my face as if making up her mind.
She looked at him and studied his face for a long moment.
His eyes were very serious as he studied my face.
He let his hand drop away, but continued to study my face.
He studied the old man's face again, trying to remember a time before his mother left.
She studied his face, and he could feel her trying to Read him.
She looked up and studied my face a long moment.
