Idk if the dots are Morse code but the binary translates to:
Lucky has been lying all this time
Argleton should not exist
Es war alles ein Experiment
Es tut mir leid, es tut mir leid, es tut mir leid, es tut mir leid

Then again, Lucky's alternate is already dead as far as I remember in the story. If I'm not mistaken there's a reveal that Anton swapped his alternate with Lucky's, then when Velvet (or whatever his name was) died, Lucky lost his reflection 'cause he's dead but not exactly. Can't remember what was Anton's fate, something about "the Machine".
Maybe we have some really bad news heading our way, or a genius twist in the story.
