They might not be strictly human, at least the type she's familiar with, but how is Patch to know that they aren't remains? The only robot in her world was built by an alien to guard over a group of hive-mind messiah children (not that she knows any of that) while the rest of humanity has not evolved past the Farnsworth tube and optical fiber. This is a head. It might be the weirdest damn head she's ever seen, but it's a fucking head.

That's an actual physical object rattling around inside a box, and that object is a damn head!"
