(These events took place years ago, names used are from my current knowledge) before I got into homestuck, all I knew about it was internet hear say. Then I find some fan art that has a lot of john and vriska in it. Then I found some that have jane and vriska. My brain made the "logical" leap and had john and vriska being a couple and jane was their daughter (?). Truth be told the artist did make vriska look older when she was with jane.

Pffft, misconceptions before getting into Homestuck are one of my favorite things. When I got into it, I got into it because it just updated with Dirk: Unite JUST as I was watching a friend livestream some art. The issue is, the quality of the stream was so awful I got a frame every couple of seconds, and without a single context I had no clue what was going on.
