They're under a ruined overpass when he spots it, next to a quietly burbling stream.
"Hey, 2B, look at that."
"Responsibility, protecting people, the physical training, the - respect probably. Being able to do something instead of run."
"Pods. Close support units. They handle heavy ranged weaponry and long distance communication."
"I understood 'long distance communication'. How does 'heavy ranged weaponry' work they're so small. 'Close support units'?"
"If we're trying to remain hidden it would be unwise to demonstrate their capabilities."
"I could hide us? Or we could try communication by mind a bit, though might not be the best idea at the moment.
Or we could wait till we find a place you like, I guess, there's not really a hurry."
(Though that sounds like quite a thing to see, even if she has no idea what kind of thing.)
"Pods more than one hundred meters from their designated YoRHa operative will deactivate."
"I mean, I could probably figure out how to hide that if I had to, but if someone happens to come by and sees an exploded tree, they're going to think 'Beasts' not 'metal people from another world who have superweapons and want to free mages'."
2B's Pod turns to face it, and a small tube extends from its bottom. Then suddenly, it flashes out rapid fire with a series of loud staccato bangs. A horizontal line across the middle of the tree is vaporized and the top half begins to tip over. A port opens in the middle of the Pod and a searingly bright beam lances out, cutting vertically up the section of tree that's still rooted. The trunk cracks in half and begins burning. A group of micromissiles jets out of the top of the Pod, impacting the top of the tree and exploding as it hits the ground.
