The image of Chetney in werewolf form sprinting to the rest of the group with a smiling FCG who's also waving at the group tucked under his arm is hilarious
I feel like Sam’s been holding this move in his pocket ever since Imahara Joe told FCG he had a bomb in his chest. That said, I think this was about the most brilliant way he could have deployed it.
Think about it—FCG wakes up in a cave surrounded by the corpses of his dead friends, only to learn later that he was the one who murdered them. Now he’s in a cave with his new best friends, and he’s going killbot mode again, but this time, he’s fully aware of his state of mind, and fully in control of his decisions. And in picking his target, he saves all of their lives.
