Each Wednesday, we discuss an older entertainment property, and currently, that's Lost. This episode, "Tabula Rasa," focused on flashbacks to Kate's back story, so we learned more about how she was pursued all the way to Australia by a U.S. Marshal (if not exactly why she was in his sights). We also saw a real parenting win when Locke recovered Walt's dog, but let Michael be the hero who reunited the two.

Next Wednesday, we'll discuss season 1, episode 4, "Walkabout." We'll be back tomorrow with a roundup of some of our favorite segments, like a library find and a visit to our archives.
