User blog:Shadowneko/Dabyi's shadow in Episode 5

Did anyone notice that Dabyi seemed to be the one who dropped off the letter from "DB"? You didn't quite see the mascot but Dabyi's shadow was in the door frame window(and I wish I was home to add a picture). This kinda lends credence to a couple of theories:

1. Dabyi is DB (someone put this theory out there already) 2. DB knows what's going on like Sebastian does

Another thing is the DB seemed to know Mana instantly when she walked into the dressing room. What do you guys think?
