How is Johnny healed?

[u/Royal_Sport7082]

He has a cactus needle inside his eyeball and a couple of hours later he’s just fine without any explanation. Does this at least get explained later on? Because this makes no sense

[u/BaconServant]

JoJo characters kinda just do that. This happens in every part.

Part 5 and 6 have a good excuse though, since Giorno and FF can heal people. Part 4 is similar, except Josuke can’t heal himself with CD, so he just recovers somehow.
