As we ponder whether the newly gentle adult Ben will remain that way, his 1977 self is causing trouble just by going missing from the infirmary. Who took him? Hostiles, perhaps. But just who, really, are those Dharma newcomers Kate, Jack and Hurley? Horace and Radzinsky, among others, might be asking, and it's security chief James LaFleur who'll be on the hook for answers. In other developments, Miles is the flashback star, and we can expect to see what Daniel Faraday has been up to lately.
