Yay, this was so adorable. I love Sherlock and Abby together. And the fact that while Abby learns some things from Sherlock, she also takes the opportunity to teach him things about the solar system and such. :)

I like how he’s always grooming her to think critically about her surroundings:

Sherlock grinned. "That's good. Never accept data without visible proof," he said.

This was my favorite line, though:

"You can do it!" Abby said, throwing her arms up in encouragement.

Abby is so sweet.

Lovely story, as always!
