‘Supernatural’: Sam kills Grandpappy Campbell

After making a deal to drag his sorry ass out of hell on the off-chance he could see his daughter again, there was not really any love lost between Samuel Campbell and his grandsons, but Sam had spent a year hunting with him, getting to have a sense of family like he always wanted. Sam technically killed Samuel in self-defense when the elder man was infected by the Khan Worm, making it a quick reflex kill, showing just how agile and “act first, think later” a hunter Sam had grown into.
