Since you inherited inferior genes,
I don't consider you my brother.
Mit deinen minderwertigen Genen …
Du bist nicht mein Bruder!
Dado que heredaste genes inferiores,
no te considero mi hermano.
Heredaste genes inferiores
y no te considero mi hermano.
Tu as hérité de gênes inférieurs,
je ne te considère pas comme mon frère.
Visto che hai ereditato geni inferiori,
non ti considero mio fratello.
Como herdou genes inferiores,
não o considero meu irmão.
