Nikos, Kostos. She probably knows how to tell identical people apart, all things considered.

As for Hanzo, she glares at him with a knife between her teeth, although there's the possibility, the potential, for the expression to seem on the endearing side of the grumpy-incredulous spectrum, rather than the potentially murderous one. Of course the foolish dragon man won't go. He is too stubborn.

Helena, for her part, knows nothing about stubbornness.

And then— it's not that she disappears, so much that she's very good at not being noticed. There's something of a feral cat to her, looping around the men until she is outside their fielding of vision, and then slinking up behind them, sudden as the mavka. No shadow and no reflection to betray her, only her wild, sharp self. But they are getting too close to the others, could be seeing them if they look sharply, so she leaps onto one of their backs.

That should be distraction, she thinks.
