It is the oddest sort of connected thoughts, but when Quebey discussed the nature of magical girls in Madoka’s universe (episode 6), it spelled out much like a more logically constructed D&D-style lich. In other words, QB makes them into liches.
And once I made that connection, there is nothing really shocking about it. I understood why it is a dramatic moment, that it broke even Kyoko’s poker face, but it wasn’t a big deal. It’s much like how Homura just went and got it, what’s the big deal?
When Urobuchi’s magical girls polish off their soul gems-slash-phylactery with magical grief seeds, what is really happening? What is QB doing with them in his magical container sort of thing? I guess souls are delicious.
