In contrast, there's little joy in Katia. She's all tension and focus. Her stature, in the smoke, makes her hard to notice, and so she lunges forward and slices through the second guard's knee, moving past the one who's been struck with the confusion gas for Clarisse to finish off.

There's one more door between them and the vault of the treasury. It's not necessary to bust all the way through, of course, but they have to make it look like they gave it a real try. So Katia starts getting to work on that, packing the hinges with explosives, trusting the others to keep the next round of guards off her.
