Ohh!! Here you go anon. Thank you so much!! I have totally forgotten this… thanks for making everything clear! (:
You people are amazing! You notice always everything… i hadn’t even noticed it! Anyway i searched the web and the only result i’ve found so far was this page HERE. It doesn’t give a reason why the number on the uniform changed… it says that it happened in episode 1x13 but we don’t know why. I guess that there’s not a particular reason but i can be wrong so if anyone knows something please tell us! ;D
