When Nick started talking about the steel door, Julian became very interested.
Nick could tell that Julian was enraptured in the story by the fact that his mouths were not flowing as smoothly anymore.
Instead, they were sometimes flowing faster and slower.
This happened because Julian was no longer focusing on "appearing beautiful and mesmerizing".
"And you went inside?" Julian asked.
Nick nodded.
"What did you find?"
Nick told Julian about the piles of dust, the weapons, the steel armor, and so on.
However, there was one thing he was keeping secret.
And that was what he had seen on the monitors.
These things were going to be seen by Aegis, and Aegis was humanity's biggest shield.
Nick was willing to tell Julian about the building and what it contained, but he didn't want to tell him about the information from there.
