I mean we probably will saw Earl awakening, and that chapter will come out on Halloween. I mean, there's nothing better to do on Halloween then read or reread/rewatch D.Gray Man. I just hope that Hoshino health got better and she will release 30 pages chapter, at the very least. Ofc it could be otherwise...but I've got strong feeling that flashback end is near. In worth case scenario it will end in next year. But from that point plot finally will move on...and I hope we will see soon Mansion and of begining of Three Days of Darkness with it's climax World End.
