@Chrono you should read again all the covers and you would see something is wrong. It is wrong for a lot of reasons but one that cannot be denied : how do you explain Brulee saying to Cracker Reiju and Ichiji are on Cacao while at the same moment they are running to the lab to free their brothers ? Let’s say the shadows are Judge and whoever else. Why Brulee would say it is Reiju and Ichiji ? This is nonsense. They have arrived to the lab right after the pages burnt, meaning they are not the one who caused the burning of the books.
I respect the one denying it is Blackbeard but it is being very naive according to the way Oda drawn the cover story since the beginning. (Silhouettes in front of Brulee and Oven arriving at WCI, weird behavior of Oven at the lab, weird behavior of Brulee with Cracker, Reiju and Ichiji who would teleport…)
