Deep Geeking: Edmund joins Tim and Summer for episode geeking this week, covering "Walkabout", a bridge episode that packs a lot of punch in some areas and that seems to fall off pace in others (in Summer's opinion, anyway).

We see Dr Franklin, hanging around in Down-Below, searching for something, but not quite sure yet. What he finds for a time could be a reflection of his own situation, or something else entirely.
