Flashback: Boone, Shannon, and Sawyer
Goofs: When Boone is tied up with his right arm in front and his left arm at his back, just after Locke leaves, Boone tries to lean over to reach the knife. However, in the close-up of his back, it's his right arm that is tied behind him. The same flipped shot is used later, three more times, when he "hears" Shannon scream.
Title Meaning: Boone must overcome his heart and his mind when faced with a task by Locke, and must overcome his love for Shannon.
