Based on this update,
I really think the big homestuck endgame,
when they all go through the door in to the new universe,
is that all the alternate selves, the doomed ones, the sprites, the dream selves, the alpha and retconned alpha, the post and pre scratch…all of them, for one player, will merge.
That is the real point of the game, the purpose of the dream bubbles and alternate timelines. It’s all to serve the ultimate purpose of allowing multiple versions of the payers to reunite and merge in to one person with the wisdom of several lifetimes. Once a player is created, by the game itself mind you, the game just serves as the vehicle by which they becomes gods; true gods. It never truly allows them to die, banking their souls and allowing them multiple opportunities. In the context of the game, death doesn’t really mean anything, or it isn’t supposed to; as if LE destroying the ghosts wasn’t bad enough, he is actually taking away bits of their personhood by destroying those alternate selves.
But all the players, they live and die and fight and carry on, and in theory the idea of an “Alpha” timeline seems to make sense, where those in that timeline are the “real” players who get to win, in actuality it’s all irrelevant. Those players’ victory is the victory of all iterations of them throughout paradox space. No sacrifice or failure is forgotten, everything is completely vital to the final person they will become when they are gifted a new universe.
