I have seen the Abominable Bride, and to be quite honest, I didn't care for it at all. I've been without a Sherlock fannish brain for a little while, and I'm afraid it didn't get rekindled by the Christmas episode. :-(

The Trio multi-chapter fic was lost in a flash drive crash in November, along with all my other stories, and I don't think I can rebuild it again. I've had to start over again with everything.

As for teen!Abby and Sherlock, I have had thoughts about that in the past, and I may indeed do something with them, someday. I sort of know about Abby's future life, so I may age her up at some point.
