Tamamo, then. I like the sound of it.

[With a little bit of distance, he got a feel for the strange vehicle, and he started driving it in the direction it had been facing. Not like they had any compass or navigational equipment, so one way was probably just as good as the other.]

Not to be all business, but the first thing we're going to need to do out here is find water. Do me a favor and let me know if you see any cactus plants in the distance. ...Or if you happen to see a convenience store. If you see one, drinks are on me.

[That seemed unlikely, but a little humor in a bad situation couldn't hurt; morale was going to matter out here. Might as well try to keep it high for as long as possible, even if his mind was focused on finding something, anything, that they could use.]

So, Tamamo. While we drive, tell me a little about you?
