When Sophie enters the living room, she finds Akari and Hinata staring tired and defeated at the table.
She then finds out that summer break is almost over, yet almost none of their homework is finished, 
which is why the two of them are doing a homework marathon.
Then, with progress already being slow, Erie makes an appearance.
She suggests that she could help with the homework, however...
I thought your memory was just 
getting bad since you're so old.
خلتُ أنّ ذاكرتك أصبحت سيّئة بما أنّك كبيرة جدًّا
Ich dachte, du hättest es vergessen,
weil du schon so alt bist.
Pensé que te fallaba
la memoria por tu edad.
Pensé que te fallaba
la memoria por tu edad.
J’ai cru que tu devenais sénile,
avec l’âge.
Pensavo che la tua memoria stesse peggiorando,
visto che sei così vecchia.
Pensei que já estava esquecendo
as coisas por causa da idade.
Я-то думала, у тебя с памятью 
проблемы от старости.
