Can someone explain to me THIS about the ending?
What I'm trying to figure out is why Nate and company left all of the treasure and never went back for it.
Like, okay, the ship explodes (all that flammable gold, I guess) and presumably sinks as the cavern caves in. Fine.
But it's not like it vanished through a wormhole. They know exactly where it is. And hey, Nate is now even co-owner of an underwater salvage company.
So...why does no one ever go back to salvage the treasure? Especially since Sam was so obsessed with it?
Is there something that I missed? Some reason why this could not be done?
