Iarwain, words cannot express the level of my jealousy! I visited Melbourne two years ago and I really hope it's something I can repeat - what an amazing city in an amazing country. And if there is a next time, the animal sanctuary will be on my itinerary.
As for the story - yes, the boys chattered a bit more than perhaps they should have but I'm not sure how much they actually gave away. There are two boats - well, that's about to become common knowledge. They're travelling back across the Pacific and through the Panama Canal - well, it's the only sensible route.
They didn't tell Gray which boat they're on, I don't think, so what did they tell him that he didn't know or couldn't reasonably guess?
Lisa and Joel, on the other hand, are about as stupid as it's possible to be. OK, they don't know that she's one of the Cartel leaders, but they can't be under any illusions that she's not a nice person at all. They know that she had no qualms about shooting down the police helicopters or feeding Henry to the alligators. And yet their first instinct is to go looking for her. Beggars belief!
