Jackman: Like all nanites, these function as part of a hive mind. That’s how we managed to even kill them. I dissected one, and it turns out that their internal circuits weren’t affected by the EMP’s, but their external radios were fried. They shut down when they lost the hive connection.
Eddie: Thing is, we can’t see any reason for them existing. They don’t have any medical equipment, all they can do is multiply and bind to pathways in the brain. The only possible use for that tech is to conquer a planet by using the inhabitants as your army, since they won’t attack each other.
Kid: Actually, maybe it’s a good thing those three weren’t here when you told us that. All they would have heard was “shoot everything.”
