Dark!Nano brought back from the dead by the Hats as a sort of spirit, albeit with very limited memories, so she follows them and goes over to the hats' side.
Honestly, I don't trust Smith enough to be able to pull something like that off. He can barley can boots of the traveler without creating mass amounts of flux!
But it would be quite cool to see something like that happen. It would make for some interesting stories
