These are beautiful. Watson in particular broke my heart in just about every single one. I'm not sure if you intended them to be expanded into longer stories, but I personally like them the way they are. They're a great example of the "Five Things" style of story; I love how in each one Holmes and Watson are progressively closer to each other and closer to the truth about each other and their relationship. I also like that they get bleaker and bleaker until the last one, which is full of hope. And I thought the scene in the jail was wonderfully subtle and very in character, for such reserved men in such a time and situation. Fantastic work.
