Grey: Well, you see, a Sioux warrior thinks, like Samson, you cut his hair, you cut his strength.
Referencing the Biblical strongman whose story is told in the Book of Joshua. An Israelite, God empowers Samson with great strength so that he can smite his enemies. He eventually falls in love with a woman Delilah, who is bribed to learn of Samson's one weakness and tell his enemies. Once they cut his hair, he loses his strength and are able to capture Samson, but God gives him strength to bring the temple down on himself and the Philistines.
