Car
Leo tells Milly that David is a doctor, and then confiscates the medical textbook that David is reading. Milly is interested, but David doesn't want to talk about his career. He bickers with Milly about TV doctors and their inaccuracy.
Milly asks to stop to go to the loo. Leo protests that they only stopped five minutes ago, but gives in.
Gas Station
David protests to Leo that Milly is really annoying, but he just laughs. He says that at least David is getting some human interaction(!) and at least she's a babe. He insists that he brought Milly for David, but he'll have her if not(!)
Milly comes back and gives David a coke. Leo asks her out to a restaurant tonight and she agrees.
Outside motel, the following morning
It's early and the kangaroos are jumping. David has been for a walk to get some breakfast, and is surprised to see that Leo is already up. Leo bustles him into the car saying he's already packed his stuff. He tells David that Milly has decided to stay on to catch up with a few friends.
As they drive away, Milly comes along and looks upset to see them driving off without her.
MILLY: Fantastic(!)
She puts down her bag, dejectedly.
