Well. Dirk's head has been cut off. And delivered. Jake's head is still intact though. Perhaps this is one of those red herrings which swim through the veins of uu.
Theory: The B1 players' quests will be completed on the B2 players' worlds, on the grounds that we've seen one firefly be freed on LOCAH. John never quite succeeded in freeing the fireflies more than temporarily, Rose never did anything at all with playing the rain. Someone has to play some rain. Then I have no real idea what LOHAC's quest was, something to do with caledfwlch I guess? I dunno. And LOFAF's quest was the frog breeding I guess, which better get done, otherwise B2 loses.
Mostly I just want to know what the heck playing the rain even means.
Theory: Gamzee is about to pop up out of nowhere, timetravel Dirk and Roxy into the future, and throw weird stuff into one of their sprites.
I remember someone having a theory about uu seriously being the Waste of Time. Well, on this page: http://www.mspaintadventures.com/?s=6&p=003256
we see Karkat, about to play a game which will lead to the creation of the B universe frog, in which uu will be, whom many people believe to be LE, who wears an oversized coat. And is colossal. And causes serious tense problems.
EVERYTHING YOU ARE ABOUT TO DO MAY PROVE TO HAVE BEEN A COLOSSAL WASTE OF TIME, the Waste of Time here being a colossal version of uu.
this makes sense
