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.
Josuke probably doesn't 
want to see anyone right now.
ربّما لا يريدُ جوسكي أن يرى أحداً الآن
Jōsuke will im Moment
sicher lieber allein sein.
No creo que Josuke quiera
compañía en este momento.
No creo que Josuke quiera

Josuke ne veut probablement
voir personne.
Sicuramente ora Josuke non vorrà vedere nessuno.
Imagino que o Josuke 
queira ficar sozinho...
