Dal and Jack in “Unfinished Business”

There's no one out there Jack, that's why you can't hear anything.

Don't be stupid. This radio can pick up stations from all over the world!

That's what I mean. Remember those last few days? The virus was everywhere. It spread too fast. Nowhere was safe. Think about it, Jack. If there were any adults in the world, what would they do? There's no TV, no internet. The radio would be the first thing they'd use. Just like you're doing.

They can't all have gone. Not all of them!! We've got to keep trying.

Jack, we're on our own.
