Thanks everyone You all rock. I would never have finished the thing without all your encouragement.
@Graven Yeah. There are places I would have liked to add more and expand the narrative, but in both cases I felt like actually it detracted from the structure.
Mainly, I wanted Rose and Kanaya to talk more - however, I had an aesthetic objection to putting too many huge chunks of pesterlog in this story (breaks up the alternating POV I was going for), and I didn't want the plot to degenerate into a huge shippy mess - I like Rose/Kanaya too much to restrain myself, but it was crucial for psychological consistency that Rose doesn't have any other relationships to save her from herself, as it were.
I was also considering putting in an Epilogue - and I may yet write this, actually - where Rose and John bond over the fact that they both have to deal with horrorterror tanglebuddies time whenever they sleep. But I thought that seemed too kind and hopeful for this installment
