JoJo no Kimyou na Bouken Part 4: Diamond wa Kudakenai EP2 - Josuke Higashikata! Meets Angelo

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.
