Elena said something along the lines of "This is my favorite spot" on the cliff. How is that her favorite if they are always moving around? Just a thought...
The nomadic people in the episode (Gypsies?) could in fact periodically cross the same places, in the manner migratory birds migrate during the season.
Yuji and Elena obviously slept together but for some odd reason, Yuji is still fully clothed when he gets out of covers yet Elena is nude. What's up with that?
Yuji : Dammit! I thought you said this ride was gonna be a piece of cake! Dice: It is a piece of cake or it would have been, if someone hadn't decided we should drive into this sandstorm! Dice looks accusingly at Marlene.
