That was not Uncle Junior on the stairs.

I had just started watching "The Sopranos" that season (recommended by Don Cardi). This was when we were on the old, old boards and nobody discussed the show then. To get a better understanding of this new show (for me) I used to visit another message board which dissected each show in detail. Someone from there found "proof" that the man on the stairs was nothing more than an extra who just so happened to appear at that particular minute.

Now, you may have seen Big Pussy in the mirror, and that was intentional (when Tony opened up a closet door), but thats another story.
