Chris, Bill and others in “Little Girl Lost”

What happened?

Bill

I pulled you out. Half of you was still here.

You mean to say you had a hold of me all this time?

Bill

That's right.

Oh, Bill. You know I didn't even feel you? Say, listen, why didn't you want me to reach in there?

Bill

And how come I kept telling you to hurry?

Yeah.

Bill

[bangs on the wall four times] That's why. It was closing up all the time you were in there. Another few seconds and half of you would've been here and the other half...

The other half where? The fourth dimension? The fifth? Perhaps. They never found the answer. Despite a battery of research physicists equipped with every device known to man, electronic and otherwise, no result was ever achieved, except perhaps a little more respect for and uncertainty about the mechanisms of the Twilight Zone.
