SORRY this turned out so big … if you can’t read the text i suggest copy + pasting the url and just zooming in from there
anyways here’s a messy chart as to how i think pearl killed PD. i also like the theory that pearl somehow helped rose get near PD, where rose killed her; you can use a lot of the arguments here to point in that direction.
whoever the real killer is, though, i’m almost certain that pearl was involved in some way. as a bystander, a conspirator, whatever.
