[A tinge of boredom as he explains.] "If Kira knew we were here already, he’d likely have had the means to killing us by now. Though, I do believe he needs both a face and a name to accomplish that...so even if that were Kira on the other side of that door, we’d be safe. So long as he doesn’t know our full names, of course. "
