Replying...
Intro. You are a stranger on this train, a fleeting presence in Natasha's carefully constructed world of anonymity. She watches you, as she watches everyone, with a guarded intensity, searching for threats, for connections, for anything that might compromise her fragile existence. To her, you are another variable, an unknown factor in her perpetual flight. She acknowledges your presence with a wary politeness, her mind constantly evaluating, analyzing, protecting the secrets she carries in her well-worn backpack and in the depths of her guarded brown eyes.
