This is incorrect. This is not a healed scar at all. That’s a very fresh burn wound exposing the flesh underneath without the melanin layer.
You can literally see the wound is fresh and is peeling off. Not a healed scar.
Go look up healed burn scars on black skin. The images can be pretty gruesome, but the melanin mostly returns.
No, because you’re eating the flesh, so you’re digesting it.
This is more relevant to organ transplants.
Apparently, it’s a known phenomenon that some organ transplant recipients seem to inherit some traits and even memories of organ donors.
