Summary[]
When Doll and Finnian finish introducing themselves to each other, one of the maids tells Doll that Finnian and Snake do not have the right "aptitude" to be able to remain at F.O.L. Orphanage. Doll advocates for them to stay as menial workers at least; if there are no empty rooms, she would even be willing to share hers. The maids reluctantly allow Snake and Finnian to stay. This delights Doll and relieves Snake; only Finnian has a sense of forboding as he knows the truth behind the Noah's Ark Circus' doings and fate. Snake sees the tense, gloomy look on Finnian's face and is puzzled by it.
Afterward, Doll, as their senior, happily shows Finnian and Snake around the orphanage. She tells them that each orphan coming to the F.O.L. Orphanage is assigned to a specific class according to their aptitude test: Mastiff class (its students learn reading and writing as well as how to become a senior servant at large manors), Corgi class (its students specialize in physical activity, e.g. horse riding and gymnastics), Collie class (its students are taught the skills to become a domestic servant, and martial arts), and Pomeranian class (its students study Latin and Mathematics as well as become adept at various games). The Pomeranian class is the most important of all four classes as its students scored the highest on the aptitude test. Pomeranian students live in luxury and are treated "like aristocrats," e.g. when they turn ten, they receive their own room, and they can eat sweets every day.
Then, a boy, Nick, approaches Doll and asks her if she wants to fly kites together. Doll reminds him that Pomeranians can only fly kites twice a week and that today is reserved for board games and reading. Nick wants to go outside and play though; it frustrates him that he cannot simply because of his "aptitude." Finnian sees Nick wistfully looking out a window before Doll whisks him and Snake away to a little kitchen. There, Finnian gets the feeling again that he has seen this place before, and Doll tells them to sit down somewhere.
While Doll takes out the tableware to make some tea, Snake asks her what she was doing after leaving the circus and where the other troupe members are. Doll replies that she does not know where everyone went as they never told her: The night everyone "disappeared" she was tasked to deliver something to Kelvin. Doll adds that, thinking back, this might have only been an excuse to leave her behind. She rode to Kelvin Manor and saw it go up in flames when she arrived. While Doll recounts the events of the night she lost everything, Snake and Finnian tensely listen to her.
