I think Jay canonically not dying even once in the entire show is really funny.
But also it gave me the idea for my fave headcanon for him ever a while ago so, Jay fandom this is for you;
Unless Jay gets any of his vital organs damaged [Ex. him getting large amound of sea water in his lungs in Seabound], he can't die.
If he gets thrown/crushed by something and his heart enters cardiac arrest without damage to any of his organs?
His lighting powers would just, automatically re-start his heart if it were to stop.
Not only that, but depending on the wound and the organ, his lightning can also turn off his nerves because of the sudden adrenaline rush, so he can't feel the said pain unless the adrenaline wears off.
If he were to get beaten to death, he can't die unless his entire body bleeds to multiple organ failures and he won't feel the pain of it until he loses the adrenaline rush he's in due to the said blood loss.
TLDR: Jay's lighting powers are his built in Defibrillator unless he fucks up his vital organs and bleeds to death/organ failure.
