As an AI language model, I don't have personal views or information about events, but here is what I know about the manga chapter:

D.Gray-man chapter 219 is titled "The Heir of Wisdom." It was written and illustrated by Katsura Hoshino and released on December 24, 2016, in Weekly Shonen Jump magazine in Japan.

The chapter picks up from the previous one, where Allen Walker is facing off with the Millennium Earl in his new form. The Earl reveals that he has finally found the "heart" of the Akuma, which he believes will help him to create a new world.

Meanwhile, the Noah family members are also gathering to discuss their current situation. The Earl's new power and the emergence of the heart of the Akuma could have dire consequences for both the Exorcists and the Noahs.

In the end, Allen's Innocence awakens in response to the Earl's power, and he continues his battle while reflecting on what he has learned about the true nature of the Akuma and the Innocence. The chapter ends on a cliffhanger, leaving readers wondering about what will happen next.
