Who's+the+Lurker?

I think is my worst fear about this web site. How does it end? This whole site is a spoiler, but just incase:

SPOLIER ALERT! SPOLIER ALERT!!!

Ok, not much of a spoiler but I remember at the end of the series three people met in a room and all wore dethboy outfits. It was certain one was The Lurker, but the question was which one. I forget who the three ended up being or if it was ever discovered which one was The Lurker.

I'm trying to find at least that missing chapter. If you have it or know someone who does please let me know!!!
