Moving forward, Katerina could only watch with wide eyes as the girl before them swept into motion, gone in the blink of an eye to defend one of the girls who seemed like she had been in trouble. It took the Russian off guard, both the sudden motion and the crack that accompanied it, the sound of just how fast she was moving in the first place. Just what was going on here right now?

It was obvious that she was not in Russia, and she did her best to grab back on to her wits before anything happened. At the moment it seemed she wasn't being pursued by these....things, these phantoms, so she had more breathing room than the others to work with overall. Not that it made a difference in this situation, since what were her options?

"Understood," she relied in Russian, nodding at the oddly dressed girl as instructions were given out for them to flee. She would not hesitate to do so, only making sure that the girl who had been attacked was taken care of first. That she was, and now it was time for them to leave, as rapidly as possible. 

So she ran, ran so that she could see her sister again, headed in the same direction as everyone else. She wasn't sure what would come next, but for now she went along with it. Fear met determination to spur her along, and she did not resist.
