The tension they built up there was extraordinary. For weeks we've been wondering what side she was on. Then her reaction to the text, the music on her elevator ride up (a leitmotif we've heard before), the background in the elevator that looked suspiciously like the red room (as a lot of rooms in that hotel seem to...), the constant foreboding for weeks that something was gonna happen to Gordon, or Albert, or both of them, the gun in her purse, right next to her cigarettes, the way she was shaking as she spoke, like there was something she was being forced to do that she didn't want to do, Albert giving her a drink and being certain to catch a glimpse in her bag, the moment she reached in and pulled out the cigarettes...
