Having reached a place he can't return from, Subaru realizes just how much he has been given and how little he can do to repay any of it. After remembering what he must do, he says goodbye to Kenichi and Nahoko and heads to the school. Steeling his resolve, Subaru opens the door to the classroom, where he's greeted by Echidna in a school uniform. When Echidna says he arrived much sooner than she expected, Subaru responds that she looks good in the uniform.
I wouldn't have been able to 
sleep in my room, anyway.
ما كنت لأستطيع النوم في غرفتي على أي حال
Ich hätte in meinem Zimmer
eh nicht schlafen können.
De todos modos,
no habría dormido en mi cuarto.
Bueno, en mi cuarto no habría dormido.
J’aurais pas réussi à dormir,
de toute façon.
Tanto in camera mia non sarei
comunque riuscito a dormire.
Eu não conseguiria dormir
no meu quarto mesmo.
В своей комнате я бы всё равно не уснул.
