The Direct Answer
Sebastian is Eyk's first mate and a hidden agent of the simulation's control structure, secretly following Henry's commands. This matters because 1899 gives each mystery both a plot function and a deeper question about memory, identity, grief, or control.
Why It Matters In The Story
This question connects directly to Sebastian, Captain Eyk Larsen, Henry Singleton. Understanding that connection helps explain how the Kerberos voyage, passenger memories, and 2099 reveal fit into one system.
Hidden Meaning
The deeper meaning is that 1899 rarely uses mystery for surprise alone. The clue points toward a world where reality can be designed, trauma can be repeated, and awakening may only reveal a larger prison.
