It's truely been an epic journey for this action packed manga. And in light of the recent implications of Mana as the 14th, i want all you people out there to look back at chapters 36 and 37. In particular chk out ch36's page 13-15. For the very first (and as of yet the only) time we see the "D" (from the title "D. Grayman") on Allen. The skull of what appears to be an akuma (chk out the pentagon on its head) emerges from his cursed eye and evolves his abilities. Moving on to ch37, the very first pages (2-5) show Allen reminising on Mana, who incidentally is blurred so we dont get a good look at the guy, and the spiralling image of Mana into the image of the akuma skull.
So whats this all mean? Allen simply feeling guilty for turning Mana into an akuma and evoking his own hidden abilities? Or possibly something deeper such as the spirit of Mana (akuma or noah) guiding and protecting him all the way.
I'd also like to cite Allen's special innocence in protecting Allen when he was stabbed in the heart by Mick and remaining intact (kinda) wen it was crushed. A possible relation to the curse/Mana/the 14th? Who knows! (Hoshino Katsura)
Anywho i'd like to know everyones thoughts.
