They do find another, and soon--perhaps suspiciously soon. Yelena will spot a shadow woman lurking in the deeper darkness, one that does the usual lurking hunt, that appears and disappears and moves ever closer, just as though she were encountering Yelena for the first time and just as though she sees her as a viable victim.

Her approach is nearly silent, though not quite; her feet touch down a short distance behind him before she breaks into a run, giving him all the warning he'll receive.
