They have said that it was an extra that used the bathroom and accidentally came down during the take and saw they were filming and then went back up. Instead of cutting it out, they left it in, thinking it was funny the actor had a reaction that made it seem like he was avoiding the awkward scene with the "remembrance" of Livia and not because he didn't want to blow the take coming down the stairs. Just a "happy accident" that worked out. I love that guy's "oh shit!" reaction. I thought it was Uncle June at first. *it's not*
Not saying I don't believe you, but I'd love to read where they talked about that. Was it on DVD or in print or something?
I don't remember where I read it, it was a few years back now, but it was straight from the person that directed that particular episode and they were specifically asked about that scene and Pussy appearing in the mirror. I just remember it because of how that complete accident perfectly fit the scene so well. That guy probably couldn't have pulled off that reaction on purpose and they obvioulsy wouldn't have thought to have him do it in the first place.
And it's clearly not Uncle June, Carmella wouldn't have had him in the house at that time and I doubt he scaled the wall and came thru an upstairs window. He would have been included in the scene had he been in the house.
