Episode 1: The Fourteenth
In D.Gray-man HALLOW episode 104, “The Fourteenth“, the series ended up in 2008.

This episode starts with a high-stakes game of chess in a graveyard and moves to the Black Order’s new headquarters. It ends on a shocking development in Walker’s relationship with his master, Cross Marian.

Episode 5: Alma Karma
In D.Gray-man HALLOW episode 108, “Alma Karma,” we learn more of Yu Kanda’s tragic origin; we see how depraved the leadership of the Black Order has been in its treatment of Alma Karma; and worst of all, we learn of the Noah’s plan to use the Black Order’s own sins to destroy them.
Episode 6: Friend
In D.Gray-man HALLOW episode 109, “Friend,” we learn the chilling story of Yu Kanda’s birth and lineage; Allen Walker finds it more and more difficult to trust the hierarchy; the viewers learn a new definition for callous; and Road Kamelot comforts Allen — for now.

Lvellie extracts a terrible revenge for Allen Walker not brining Yu Kanda and Alma Karma back from the hidden place; jealousy ferments among the Noah, both at Road Kamelot’s relationship with the Millennium Earl and the Earl’s relationship with the Fourteenth; a Church Council carefully ignores all evidence contrary to their convictions and keeps Allen imprisoned; civil war ferments among the Exorcists living in the European Branch as several of the most powerful, like Lenalee Lee and many scientists, fume at Allen’s captivity, while others demand his execution; and an Arch-Bishop decides to take matters into his own hands.
Episode 11: Hidden One
In D.Gray-man HALLOW episode 114, “Hidden One,” we learn that any given Cardinal might not be quite the respectable pillar of the community that you might expect; that Allen Walker has some previously unknown relationship to Innocence that puts him at elevated risk of death; that Road Kamelot really does care enough for Allen to put her life on the line; that the Black Order’s leadership, and the leadership of the church in general, is hell-bent on ignoring fact and making knee-jerk decisions; and that Howard Link was earnest when he confessed his sorrow to Allen.
