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.
That ain't happening again, Josuke. 
I know your powers very well now.
لن يتكرّرَ ذلك يا جوسكي، أصبحتُ على دراية
كاملة بقِواك الآن
Das schaffst du nicht noch mal.
No volverá a suceder, Josuke.
Comprendo tus poderes muy bien.
No volverá a suceder, Josuke.
Comprendo tus poderes muy bien.
Tu n’y parviendras pas deux fois,
Josuke.
Non ricapiterà, Josuke.
Ora so bene come funziona il tuo potere.
Você não vai me prender de novo.
Já conheço bem seus poderes, Josuke.
