Jack is going to immediately step up to defend Nanami. "This is not their job. Sure it's their world, but none of them should ever be asked to make this decision. We didn't get asked, either, but we have more ability to defend it than they do. It's not selfishness to step up so other people don't have to. We die, we come back. They die, it's for good. We die so they don't have to, it costs us so much less."

"And I'm going to repeat my earlier point. The people, the life on this planet is what is giving it the ability to defend against the Calamity. The crystal is keeping the Calamity from spreading and overtaking this planet already. If the people die, even if we're still standing? The planet itself is going to give up the fight."
