Apologies for the delay in posting this. I’ve had some problems with my DVD playing software that are now, hopefully, resolved.
The goal of this episode seems to be to introduce two of the series’ main characters: Bolin and Mako, the probending brothers that make up two thirds of the Fire Ferrets. This has been done with a self-contained episode that doesn’t mention the main conflict in the show – Amon and the Equalists – but it does feature prominently Korra’s core personal conflict, her difficulty in learning airbending, and another major theme, Korra in conflict with a figure of authority. Using these conflicts in a scaled-down version of the overall series is an effective way to establish them and their importance in Korra’s story.
It’s a well-structured episode too. It opens with a reminder of the first episode, narrated by the same voice actor as the probending announcer, with the visuals in sepia tone with visual artefacts to give it a feeling of being old, a nice little nod to the time setting of the series, an industrial, almost modern world.
