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.

Debo decir que este sujeto
está bastante loco.
Debo decir que este muchacho
está bastante tocado del ala.
Ce gars est complètement dingue.
È decisamente pazzo, non c'è dubbio...
Ele realmente não bate 
muito bem da cabeça.
