Wow this Vriska is not like hers at all. Kanaya ignores the vague weird ache in her chest at the realization (probably just another cut), and stands with Karkat's arm over her shoulders. She probably holds him a little tighter than is strictly necessary -- she won't say it out loud, but it's a reassurance.

"This way," she directs with a wince, starting off in the direction that they had come from. It's relatively easy; she just needs to follow the fresh blood.
