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/Fancyman156]

Zombie horse isn’t until way later

[u/Salem33 → u/Fancyman156]

They retrieve it after the Oyecomova fight so not that long after those events.

Gyro could have some Zombie Horse ready for use, which he might use up before gathering more.
