Hao Ren was always curious about the "society of survivors" on the Zenith and the lunar base. But since he had never been able to contact them directly, his understanding of the society was only based on Nolan's limited observational data, which was clearly far from enough.
The arrival of N-6 brought him a great surprise, but before he could ask N-6 about the society, another "source of intelligence" was sent to his door voluntarily.
N-4 said that she knew a lot more about Zenith and the base on the moon than N-6 because of her long service life. While it did not give her more comprehensive access than N-6, it did give her more information about the society of survivors. But she also wanted more information on the background of the "space visitors" before she shared what she knew.
