"That's what the vid said," he says, but there's a dubious note in his voice, because Annie's right: this place took a lot of skill and machinery and engineering to build, and to sustain. They have livestock somewhere, and little forests, and all the other things he'd done his best to focus on through his worry: people working away like Beetee with his inventions, fish jumping out of that lake in the park, and people. So many people.

"The vid showed forests and farms, too. And lots of inventors. Guess they worked out how to do it? If Beetee were here he'd probably be able to come up with an answer." But neither Finnick nor Annie is an engineer.

Beetee, after all, had created the incredible trident Finnick is holding, that comes back to him after he throws it.

"It's like if you could see how big Thirteen is all at once."
