Something's wrong with Uesugi: his grades are dropping, he's falling down stairs, and he's bailing from Team KZ investigations.
We have to prove that I 
wasn't skimping on cleanup.
علينا أن نثبت بأنني لم أكن مهملاً في التنظيف
Wir müssen beweisen,
dass ich nicht nachlässig war.
Demostraré que sí que limpié.
Je vais prouver
que j’ai bien fait mon taf !
Dobbiamo dimostrare
che non ho preso le pulizie alla leggera!
É preciso provar que não pulei a limpeza!
