 A main theme of the episode is Kate's inability to commit to other people, always running from difficult emotional situations, and having barriers between her and her interests – physical, as in Sawyer's cage or Jack's aquarium, or metaphorical, as in her inability to settle down as Kevin's wife. Kate's marriage, which was first alluded in the season one episode "Outlaws", is meant to be a contrast with her relationship with Sawyer in the realtime events – Kate and Kevin is a heartfelt and passionate relationship where Kate tries to get involved but her lifestyle ends up on making the marriage fail, whereas with Sawyer both are afraid of intimacy and connection yet still end up together.
