Only two people knew about this, and one of them was himself.
Su Ming was certain he had never told anyone about his origins, nor did he have a habit of talking in his sleep, so the information could not have leaked from him.

The moment this suspect came to mind, many things instantly made sense.
Of course, Second Sister had once said that Manhattan was dead, and that information had to be correct. Death was one of the truest states in this universe, far more real than Dream, at least.

Blank literally meant empty, containing nothing. Compared to quantum, which was "everywhere," she was "nothing, therefore nowhere." Thus, Su Ming came up with a guess: the
