Jin is skeptical of the Man in Black and believes he is not Locke. When James, having been captured by the Man in Black, joins him, Jin tells his friend he wants to find Sun first, to which Sawyer agrees. However, Jin has no choice but to follow the Man in Black's group as they journey across the Island. Sawyer and the Man in Black tell him that he is a possible "candidate" of Jacob's (the leader of the Island and enemy of the Man in Black), meaning he may be chosen to watch the Island after Jacob's death. However, he is unaware of the Man in Black's intention to kill him, since he is a candidate. Late one night, while the Man in Black is off retrieving Sun (as she may be a candidate as well), Jin and the others are attacked by Charles Widmore's team. Tranquilized, Jin is brought over to the second Island where Widmore's submarine is docked. Jin wakes up inside a DHARMA Initiative complex and meets Zoe (Sheila Kelley), who eagerly asks him about his hand-drawn map of the electromagnetism pockets, which he drew back in 1977. However, he demands to see Widmore.
