I feel like something else that hurts so much about this is that Sherlock knows how it feels to feel like you have no one. Amid every other screaming, sobbing, and panicking emotion he's feeling, he's probably also got some guilt that he made his sister feel that way, too.
Noddy is a character created by English children's author Enid Blyton, originally published between 1949 and 1963. Television shows based on the character have run on British television since 1955 and continue to appear to this day. Noddy is a little wooden boy who lives in his own little House-for-One in Toyland and has many "special" friends. Ahh, another childhood memory!
I didn't know you could get backpacks for cats! There's no way I'd be able to get one on Bonnie.
