[Vash smiles as Knives goes over what he found. Pushing back the thought that in less then a year this is the kid that was going to nearly wipe out the human race.]

Yeah, sometimes there's hidden water under the ground. You've probably hit some really sticky and hard dirt too, haven't you? The clay?

I'm not sure exactly how much you've studied yet on the ship, but the ocean water is full of salt, so you can't drink it.

[Vash isn't in any real hurry and he's guessing he has this smaller version of his brother for the next couple weeks anyway. He squats down close to the hole, debating if he wants to sit and get dirty still or not.]

Would you like to keep digging? Or are you starting to get cold and hungry? I have a place back in town and you can stay with me if you'd like.
