Something's wrong with Uesugi: his grades are dropping, he's falling down stairs, and he's bailing from Team KZ investigations.
There's no way I could ask him "Why did 
your math grades go down?" to his face!
من المُحال أن أسأله بشكل مُباشر
"لماذا انخفضَتْ درجاتك في الرياضيات؟"
Ich könnte ihn niemals direkt fragen,
warum seine Noten so gefallen sind.
No puedo preguntarle a la cara 
por qué sacó mala nota.
Mince…
Non posso certo chiedergli
perché non è nei primi cinquanta...
É, não tenho coragem de perguntar
 na cara o que foi que houve.
