This episode pulls every emotion from you: suspense, anxiety, hope, joy, sadness, and grief. It really pulls at the heartstrings. Kate and Sawyer both miss saying goodbye to each other, Vincent is "loaned" to Shannon, and Sun and Jin finally make up. This is why I love Lost - yes the mystery, suspense, and questions keep you tuning in, but at the heart of the story it's all about the characters. The arcs are fluid and executed perfectly.
The Exodus Part I is a 10/10
