Only in the sense that they are Observations, written from the point of view of someone who doesn't know what is happening behind the scenes. Luxu of course does know the answers to almost all of the questions he is asking. A lot of half-truths, but I don't believe there is anything in them that would make Pinoccio's nose grow.
And that is presumably the same one we saw meddling with the Queen of Hearts in DR. If so, it must have just escaped to somewhere in the real world.
Speaking of Darknesses, one thing that hasn't been discussed yet is them in the modern timeline. The chess game has seven black pieces. One of them is in the MoM for sure. Another is supposed to be in Luxu, but after the face reveal I find that somewhat suspicious. Then there are the four remaining foretellers. The Darknesses inside their hearts were supposed to be destroyed in the War, but the chess pieces suggest otherwise. Or have they acquired a new set? If Wreck-It Ralph is part of the fictional world, and the foretellers went there after the war, then Ephemer and the Player sent four Darknesses into the same place where the four foretellers were... In any case, this leaves Ava, Ven/Vanitas, and the one on loose as candidates for the last Darkness.
