@bodertz i knew the kids all ran into alternate-universe versions of themselves at some point, and i assumed these versions were trolls. in my mind jade ('Doctor Hailey Scratch,' i remember thinking her name was) cloned some trolls based on her son and her son's friends, and sent them to the troll planet for some unknown purpose. i knew vaguely that genetics and cloning were involved in homestuck's story, and extrapolated from there. Hailey also spliced herself with radioactive dog genes at some point.
