Each Tuesday, we discuss an older entertainment property, and currently, that's Lost. The "two" of the title might refer to the unlikely pairing of Ana Lucia and Jack's father, Christian Shephard, or to the two castaways who lose their lives in the shocking final minutes of the episode.

Next Tuesday, we'll continue with season 2, episode 21, "?." (That's not a typo.) Tomorrow, we'll continue our discussion of a newer show, Running Point.
