Palmer's hopeful there are survivors, and is ready to do what he can to offer aid. Hopefully anyone on board will know the three are there to help. He's ready to explain himself iff he has to.

"We'd better be prepared in case there's somebody on that ship," Palmer says, grateful for the protection. Both Harley and Furiosa are expert, hardened fighters. Palmer's just a grease monkey from California, despite his previous experience in polar environments. "For all they know, we'll be there to steal it. We've gotta explain ourselves to 'em so nobody gets hurt."

The mechanic's cautious, being both the most lightly armed and weakest member of the expedition team. He feels a little like a liability. He'd be useless in a fight.

"Medicine's important," he says. "I'm with Furiosa. We gotta make sure everybody back at the shelter's got access to clean food and fresh water. Don't want anyone getting sick."

He keeps careful watch out for the ship and for the creatures he's heard about. It's difficult for him to see in the snow, even wearing goggles.
