"When Jesse's intentions were first brought into light, she called the Connor-family enemy "It ... metal!"

Sarah isn't exactly an it or metal.

Jesse hates Cameron. =P"

"So I'm re-watching S2E9, and suddenly I understand this better:

James: "Who taught you how to play chess?"
John Henry: "I did."

I thought John Henry's answer was odd, but it's absolutely correct. John Henry was bootstrapped from Turk. He taught himself in the sense that John Henry inherited the knowledge from Turk when he assumed the John Henry persona.

This would be freaky if it wasn't obviously planned: Sarah dreamed about it in S2E9. Someone who looks exactly like Cromartie (John Henry) received a turtle (Turk) from someone made of metal (Catherine)."
