It's this latter one that's quite interesting. In saving our world's Olivia earlier this season and getting her to safety on multiple occasions, cab driver Henry seemed to be in the right place at the right time. But his involvement with Olivia--and now Fauxlivia--ask certain questions about destiny. Is his fate inexorable tied up with both Olivias? It calls to mind a certain Chinese proverb: "If you save someone's life, you must care for them forever."

It's Henry, in fact, who might be the savior of both worlds' versions of Olivia Dunham, a man who has crossed paths with her so many times that he's now fated to look after her for the rest of her life. A cabbie who transported a woman who can move through worlds. A father who must care for a mother. What's especially interesting here is that he doesn't know this world's Olivia and she doesn't know him, so something bigger than both of them--call it divine intervention, fate, destiny, what have you--has engineered their meetings towards some end. And, given that proverb, it's only fitting that one such meeting should occur within the heart of Chinatown.
