I just realized something
Perhaps it’s just common knowledge, but…
I already knew that Wilson’s name is probably a reference to Castaway Island, but I just realized something else: William Carter (Maxwell) is possibly named that because of E.A.Poe’s William Wilson, where the main character has a doppelganger following him throughout his life and exposing his sins. He comes to hate the clone, and in the end, he kills it, but it turns out he also kills himself spiritually, because it was his conscience actually(?)…
Even if it’s not a reference (though why not? one of the crucial items in the game is a reference to Poe), I find it very fitting.
