When Finn was young, his family lived in a slum where garbage tended to be dumped. One day, his brother brings him an older model of Deco that should be easier for Finn to use due to his Deco-Sickness. With it, Finn accidentally discovers that the local purification systems are broken. Believing this is what has caused his home to become polluted, he uses the Deco that he got from his brother to request that the customer center fix the purification system. But because he isn't registered as a citizen, his login is flagged as illegal, which leads to his request not being answered.
You know you get sick using those 
things. Keep your face out of them.
تعلم بأنّك تمرض من استخدام
تلك الأشياء. ابقَ بعيداً عنها
Du weißt doch, dass dir das nicht guttut,
also lass die Finger von Decos.
N’utilise pas de Deco.
Tu sais bien que tu es allergique.
Lo sai che sei allergico,
Sabe que passa mal usando essas coisas!
Pare de se meter com Decos!
Хватит мучить себя Деко:
у тебя же аллергия.
