Palmer jumps as he hears the metal being wrenched open. It's a sound he's familiar with, and one where he knows what it means. Of course the creature outside wouldn't give up that easily.

He looks for the general direction of the scraping sound, handgun drawn, ready to shoot when he sees something. He's pretty sure at this point that their visitor isn't friendly.

"Any idea what's out there?" Palmer can't see what's going on himself, but he can guess that the creature is the same kind as the creatures behind the recent attacks. And he'd wanted to see them.

He's well aware that he's the least physically capable of the party, and saw the least combat. Nevertheless, he wants to make himself useful to Furiosa and Harley.
