He gives a satisfied smirk when the alarm goes off and the shadows sever the striker, but he still retreats into the shadows around him when Jack pulls the trigger - there was no need to get careless and take chances with things like that.

He flows unnoticed among the shifting shadows in the hall and reforms silently a ways behind the older man. Now that he doesn't have his gun, he is a much easier target - and after all that exertion, Koizumi is starting to get a little hungry. Although, to be honest - however much Koizumi knows he shouldn't play with his food - it is far too amusing to see him off balance like this.

He leans casually against the wall, looking bored and examining his nails, not even glancing at Jack. "I hope that gun of your wasn't too expensive. I'd feel bad about ruining it if you hadn't threatened to shoot me first.

Still, you must be worried - an escaped prisoner? That sounds serious."
