I just noticed a slight discontinuity in both the Leaving endings. In ending A Alice is not present, but right after you finish pressing the button to "Don't throw the lighter", she appears in the seat on the right hand side of the screen. In Leaving B ending it's the opposite; she's present until just after pressing the "Throw the lighter" button. Then she disappears from her seat on the right hand side.

I'm not sure if this is a small bug or discontinuity, or if it's part of the writing as symbolic in nature.
