D.Gray-man - Season 2 Episode 44

Allen and all of his friends return safely to the HQ and Miranda deactivates her Innocence, making the injuries the Noahs inflicted on the Exorcists reappear. While the excorists recover in the hospital of HQ, Bak and other scientists study the ark's ability to teleport people anywhere in the world. Allen goes into the piano room with Tim and ponders on how the symbols he and Mana created years ago were the song to move the ark. Elsewhere, the Earl becomes enraged by the fact that the 14th Noah has somehow helped the Exorcists obtain the ark and the Akuma "egg".
