Okay, I don't know if you guys paid a little attention to the episode "Night Terrors", but I've been checking it, looking for clues that might help us solve what's left of the mystery, and I think I found out something regarding Burlington's mystery solving group.
According to the book that Velma show's the gang about the Benevolent Lodge of Mystery, there's a text page which tells us the story behind this group. From what I've been able to read (the letters are too small to understand the full text), it seems that this team travelled the world looking for manuscripts (they have travelled through Germany, the Ottoman Empire, Greece, France, Britain, Belgium and many other places... they even travelled through the Far East and the Africcan continent). It also reads that the group was disbanded by Burlington himself, after Mr. Peaches, his pet orangutan died, and that he lived the rest of his days inside Burlington library.
Now the question that I make, is this what really happened, or is it like the story with Friar Sera and his donkey Porto, who blew up half of Crystal Cove using gunpowder and TNT, sending it to the bottom of the ocean... a lie? For some reason I do believe something else happened...we found Frau Abigail Gluck's corpse on thatunderwater base where the final piece of the Planespheric Disc was located, andwell, that could point out that maybe the group split because of something else, something regarding the treasure of Crystal Cove and Nibiru.
What do you guys think? Tell me your theories...
