We've already met Dan, Charlotte, Miles and Frank on previous episodes, but here we see a little of their backstory! Why is there a polar bear in Tunisia (and how?) When did Locke see a tall Walt?   What is the meaning of life?  How much bullshit is Jack gonna say?  In other words, the typical stuff.   Danielle unravels more mysteries on this episode of Lost at Random (or maybe, just unravels).
