Triggering Scarlett

You turn off your mic.

"Scarlett, is your husband expecting you back any time soon?"

"He's not home," she muttered. "He's in Europe, on business."

"Excellent. Wait for me backstage after the show."

She nodded. You turned the mic back on.

"Scarlett, hear my voice and obey. I will give you a word. If I say 'Freeze', you will freeze in place, obviously. But that's not all. While frozen you will be aware, and if I say a specific body part followed by freeze, that body part will freeze. So if I say left arm freeze, only your left arm would freeze. Understand?"

Scarlett nodded.
