Extra Story - Maria's Sight

Extra Story - Maria's Sight (マリアの視線, Maria no Shisen) is the two hundred and sixth chapter in the D.Gray-man manga series written and illustrated by Katsura Hoshino.

Synopsis
In a flashback, a much younger Allen Walker is seen, standing beside Cross Marian, saying goodbye to Mother and Ba-Ba. When Mother calls Allen by Mana's last name, Walker, Allen tries to insist that he isn't worth of the name. Cross, though, says it fits him before walking off, leaving Allen to catch up. In the present day, Mother reflects on how Cross brought Allen to her and Ba-Ba's house in order to take care of the traumatized boy, Cross going so far as to feed and change the boy's soiled clothes when Allen became completely unresponsive. When Cross is disturbed by the fact that, when Allen does speak again, he speaks politely like Mana instead of rudely like how he used to, Mother points out it doesn't really matter, as someday Nea will take over and kill Allen's consciousness, anyway. In the present day once more, Mother is looking over some of Allen's old clothes. When Ba-Ba answers the door, they are both shocked to see Allen there, Mother noticing that if Cross hadn't really cared about Allen that there would be no way he could have the look on his face that he does now.
