She tried to smile a bit at Kira but it fell short, much like the other girl's greeting. Jo wanted to give her a hug or something but given the circumstances it didn't seem like the best move at the moment. She felt an overwhelming sense of empathy for Kira though, for as much as everything seemed to be falling apart for all of them Kira had that much more to deal with.
"I.." she started to say something but another crash of sorts, closer this time, followed by a high pitched scream interrupted her. Everything seemed to move fast after that, a blur of a man racing towards them his face contorted in pure rage, completely lost of anything that looked human. Jo quickly tossed her knife to Kira, almost certain that she wouldn't be armed after everything. She managed to get her gun out before the man tackled into her and lunged at Kira.
