Futaro is hospitalized for a while after falling sick at camp school. He returns to work tutoring the quintuplets, only to realize someone has fallen way behind.
I can't believe you've been 
hiding the exams you bombed.
Y pensar que ocultarían
los exámenes que reprobaron…
Y pensar que esconderíais
los exámenes suspendidos…
Non riesco a credere che abbiate cercato
di nascondermi quei test.
Não acredito que tentaram
esconder suas notas zero.
Ещё и спрятали проваленные тесты.
