Lenny turns around to see if something is watching him as the exit to the Fourth Wall disappears completely.
Lenny, upon turning around, sees them.
Someone is indeed watching him. Actually, a great deal of people are watching him, all through what look like large windows into where he is standing. One person in one of the windows, significantly larger than the rest, is looking at Lenny, then below him, and ocassionally looks away or leaves. Lenny can hear pitter-pattering from the big screen, and he hears clicking sounds from some of the other screens as they go black.
