Aaron's visit reaches it's end with a regular chapter and then a short epilogue. (If you read this at just the right time, it's possible that the final chapter has posted, but the epilogue hasn't.)
I had some inspiration, and I came up with an extra chapter for Too Hard. I'm going to leave that one as completed, but realistically it will probably get chapters added to it from time to time as it's progressing beyond the point of a short story with a slightly humorous ending.
