Aww, this is great! I flailed quite a lot over it; it's lovely. :-)

(ETA: Also also tiniest of nitpicks, because I assume you are going to put it on AO3 where I can admire it some more, but Dr Seward calls Lucy Miss Weston, which he doesn't usually, even when someone else is there, only Lucy, because they are engaged and he's Allowed. I am currently world's best expert on this adaptation for Reasons. But I actually read this last thing before turning the computer off and it made me happy ever since, nitpicks regardless.)
