Josuke spots the terrible and violent villain Angelo's Stand, and tells Jotaro about that incident. Jotaro figures it's a Stand that can somehow enter people, so he warns Josuke to not eat or drink anything until he can get to him. Right when he's told that, Josuke witnesses the Stand go into his mother, and then does the unthinkable.
Can't your Stand heal your wounds?
ألا يستطيع الستاند المخصّص لك معالجة جروحك؟
Kann dein Stand deine
eigenen Wunden nicht heilen?
¿No puedes sanarte con tu Stand?
¿No puedes curarte con tu Stand?
Ton Stand ne peut pas guérir
tes propres blessures ?
Non puoi usare il tuo Stand per guarirti?
Seu Stand não cura 
suas próprias feridas?
