During the episode "Lighthouse", Claire captures Jin and Justin, the other. In an attempt to save Justin's life, Jin tells Claire that the others didn't take Aaron, and that Claire has been raising him. Claire kills Justin anyway, and Jin then lies, telling Claire that the others do infact have Aaron, and this was before Claire said that if Kate was raising Aaron, she would kill her. So why did Jin change his mind and say that the others had Aaron. Thanks, guys.
