Well I wrote that earlier. He even said top floor. To be fair I didn't mention it much after the first few posts though. 

Well there's about a few dozen hostages and a half-dozen or so trigger-happy thugs, a phaser named Ghost, a super-acrobat named Stalker, and a sonic shrieker named... Shrieker :P 

They are dispersed around the top floor where there are several tables along the windows and several more spread around the middle of the room, the staircase downstairs in a corner. The hostages are all seated at the tables.
