Natasha hears the voices grow more distinct - some kind of ancient chanting, like she heard at the temple. So focused is she, that she almost doesn't hear the clanking and turning of gears in the walls, but Natasha manages at the last second to pull her and her companion away, as darts begin to shoot out from the walls. There's a fusillade of the small darts, coated in poison, but eventually, their numbers decrease, and disappear entirely, making the hallway safe once more. As the sound of the darts fades, she hears footsteps coming towards her.
