I'm guessing he was "turned down" from the thing Nora is heading to. Doesn't a guy do a similar thing in the film Walkabout, as well?
The film Walkabout is the first thing I thought about when the scene happened. Brilliant film and crazy nod.
Not sure if this has been mentioned yet, but the aboriginal boy from Walkabout actually makes an appearance in Sunday night's episode.
Same dude. David Gulpilil, if anyone's curious.
