uhm so i was rereading homestuck and... after game over, basically terezi saved everyone? do you think that without terezi there would have been a way to "fix" everything or is she sort of the most important character in homestuck?

I’m sure John could have “fixed” everything on his own, but he probably would have fucked a bunch of stuff up in the process. So lets be glad TZ waited to die until after she told John what to do.
