Hussie seems to make of good job of tying everything together, so I'm not too worried. I...can't really see it ending very soon though! I'm pretty sure we still have another six months to a year. I think (??) he said there'd be 8 acts? Hmmm
I really hope that we get to learn more about the cherubs without straying too much from the main plotline. I love Homestuck, but I hope that it wraps up within the next few months, and doesn't drag too much.
