During three years in the DHARMA Initiative, Sawyer becomes Jim LaFleur -- a man of integrity, a leader, a partner. Juliet is the reason. She doesn't need him to be charming or tough; she needs him to be honest. Their relationship is the most functional and healthy on the entire show, which makes Juliet's death at the Swan site devastating. Their flash-sideways reunion -- "We should get coffee sometime" / "I got you" -- is widely considered the most emotionally powerful scene in the finale.
