I'm a librarian who loves anime, manga, and reading a wide variety of genres.

Okay, so the thing Sullivan's mom did was needlessly complex.
As for Sebastian... Yeah, there is definitely no warm, fuzzy protectiveness towards Ciel in that corner. Ciel is future food and current entertainment, and that's it. It was kind of nice to see Sebastian start to let loose a bit, and I absolutely loved the artwork during the bit where Ciel broke free of his flashback loop – Toboso can do some absolutely gorgeous double-page spreads.
