You start cutting the rope around the girl's wrists and ankles and say, "Who are you?"
The girl's face falls. "Shit, that spell worked a little too hard."
"What do you mean 'spell?' Like magic?"
"Yes, like magic. I'm Ava. Let's get to the compound, and someone there can undo it."
"And the rope?"
"I wasn't sure if I was infected or not."
You shudder, and she heads past you toward the east door.
