Well, something like that has happened to our crab. But instead of free electrons, the crab has free atoms, all disconnected.

Quote context

[...]

- Molecular structure of this crab is entirely disrupted. There's no cohesion between the atoms.

- I don't understand.

- Nor do I.

- Apparently we have one of those biological freaks resulting from an overdose of radiation poisoning.

- The way to explain it is, look, electricity. The free electron in the copper atom breaks off to circle the next atom, taking the charge along the wire.

- Do you follow me, Hank?

- I think so.

- The free electrons jump from atom to atom along the copper at the speed of light. I remember that from high school.

- Yes, atom to atom.

- Well, something like that has happened to our crab. But instead of free electrons, the crab has free atoms, all disconnected.

- It's like a mass of liquid with a permanent shape.

- Any metal, therefore, that the crab eats will be assimilated in his body of solid energy, becoming part of the crab.

- Like the bodies of the dead men?

- Yes.

- And their brain tissue, which after all is nothing more than a storage house for electrical impulses.

- That means that the crab can eat his victim's brain, absorbing his mind intact and working.

- It's as good a theory as any other to explain what's happened.
