Marjorie Mystery ... Solved?

So according to NBC's Season 4 Premiere Live Chat, Greg Daniels has in fact addressed Marjorie's presence:

Who is that lady in the background sometimes?
Her name is Luanne, she is a background player. I go back and forth about her. Sometimes I think that it was more realistic to have some people you didn't know about in the office, but as the seasons progressed and we learned so much about everyone, it got increasingly weird to see this nice woman wandering through scenes.

Dave: What's the explanation then for her disappearing?

Greg: What?

Dave: I mean, in the continuity of the show...

Greg: Oh, look, another question just came in.

This only adds fuel to the ever burning fire that flames the Marjorie conspiracy. At least we can rule out the theory that she's a ghost on the Office set. For now.

Thanks to AgusLucas for pointing this out to us.
