Well, I guess this concludes any mystique over Marten's inevitable success.
He opens a 'coffee shop' that has some sparkly lights projected on the ceiling, plays some vaguely non-chart music from a bluetooth speaker in the corner, sells shots of Draino, and becomes wildly successful as a "sensory experience" to the sheltered, pastel cretins of Cubetown who fall over themselves to throw money at him. He makes one cup of actual coffee per month, which gets mounted atop a floating black monolith who then ascends into the sky for unknown reasons.
Dora then justifiably turns purple and explodes through sheer outrage, because 10 years of putting blood, sweat and tears into your personal passion is for chumps.
