She was terribly frightened.

Again with warning hand commanding silence I stepped softly forward, meaning to reassure her.
"Russ! Russ!" she whispered wildly, and I thought she was going to faint.

When I got close and looked into her eyes I understood the strange dark expression in them.

She was terrified because she believed I meant to kill her, or do worse, probably worse.
