'Supernatural': Sam uses his tree-trunk arms to decapitate Gordon
Gordon wanted Sam dead, so it was only good sense for Sam to take matters into his own hands. Gordon had super strength as a vampire, but he proved to be no match for Sam’s own powers, as Sam twisted and squeezed barbwire around Gordon’s neck to decapitate him. Everyone always says Sam is the brain of the Winchester operation, but here he proved he has the brawn, too.
