Katniss approaches from covering the rear, looking completely lost upon seeing Nessa like this. She's seen it before plenty of times - or at least, seen Nessa take the precautions to not go too far with this kind of thing.

She glances at Karkat and Jon uncertainly, keeping her bow loaded in case they get assaulted by any more cyborgs.

"...Nessa, come on...we're here to get you..." she says softly. She feels like there is probably something smarter to do here, but she's at a loss. She swallows, and looks to Karkat again, as if hoping that he'll have a better idea.
