The girl Shiki met in the library was the same girl that he had seen riding on the back of Sasajima's bike. The book she left behind has a marker stuck to the page on building quiz bowl buzzer systems. Is she involved with quiz bowl? As Shiki is thinking about all his, Mari tells him they're having a joint quiz bowl practice with another school today. That school turns out to be Miyaura High, the team that claims Mikuriya as a member!
it felt like everyone was 
suddenly on the same page.
.شعرتُ وكأنّ الجميع متناغم فجأة
schienen alle auf
einer Wellenlänge zu sein.
parecía que todos estaban
en la misma página.
parecía que todos estaban
en la misma onda.
è come se tutti ci fossimo trovati
sulla stessa lunghezza d'onda.
senti que todos estavam em sintonia.
мне показалось, 
что мы чувствуем одно и то же.
