Something is off with Hiro's sense of time. He's constantly late, and almost misses his curfew. Ruli suggests a trip to the library for a change of pace. They meet some unexpected visitors and learn the cause of Hiro's problems.
So, why are you two here as well?
حسناً، لماذا أنتما هنا كذلك؟
Und was habt ihr beiden
auch hier zu suchen?
¿Y qué hacen ustedes dos aquí?
¿Y qué hacéis vosotros dos aquí?
Et qu’est-ce que vous faites là,
vous deux ?
Comunque... come mai ci siete anche voi?
Então, por que vocês 
dois também estão aqui?
Слушай, а вы почему здесь?
