The Grepton metabolism cannot handle large amounts of salt.
Nobody told Rufus this. Or told him the fact that Greptons exist.
He fired his rock salt-loaded shotgun at the the “college kids” who were making circles in his crops.
Instead of scaring them off, the salt killed the little bastards.
The Grepton Ambassador demanded Rufus’ extradition so they could charge him for murder.
The Deputy Undersecretary For Alien Affairs said “No.”
“They were my children!”
“No.”
Deeply hurt, the Grepton Ambassador left.
So, when you say Elvis is dead, technically you’re right.
But to Elvis, Earth is dead to him.
