This chapter went through so many iterations. at one point it was twice the length of what follows and also half the length. At one point i had scrapped it all together. In the end - it just has too much spice for the story to be deleted and i upped the stakes a lot. The first draft was just some theorizing and light weight tiny bit assaulting. Now - if L hadnt intervened, two more deaths would have happened. Well. if the first death would have happened - which would have been Barbera - then the second would not have happened, since Barbera would have caused it.
But Barbera made it out to be exactly where you see her now and right now she knows as much as you on where she is and how she got there. Nothing.
