You know, like they have/had (haven't been in a while) in Bleach.
If you have a quick question about D.Gray-Man that you don't want to create an entire thread to discuss about, just ask it here and others will try to answer it. ^_^
Sure, we can have debate, but let's try to keep it related to the last few questions asked. =P
Okay, Digi's question: Is Rabi actually related to the old Bookman, or are they just colleagues/master and trainee? Bookman says that they're both Bookman (Bookmen?) but is that the title or is that more of a family name?
