Just seeing Julia having friends warms my heart, poor girl really shows how much she missed contact with others.
Hana's aura is another part of the story that is a mystery.
The most interesting bit of information we got from this is that Miko seems not able to see Hana's aura, she seemed to have a much deeper sight but this may signify that is less about depth and more about type. (i could swear she could see aura)
