Sometimes, when Rui returns to Shibuya house, she finds a packet shoved under her door. The packet comes in a white envelope, sealed shut, with her new name and number on the front in Helvetica. The word "Code" is Romanized; likely because it is Heike doing the writing. She opens her door, scoops up the envelope, and carries it out back to go with the combustible trash without examining its contents. When she returns she finds another envelope secreted away in her bookshelf, this time a little fatter. She throws this one away as well. This is a sort of dance that she has with Heike; he will leave his judgment of her performance under her door in the days following a mission and she will toss it away without a second glance. Heike will counter by leaving a second envelope containing all of the reports that she has ignored in the past somewhere in her room along with a note threatening to punish her for being a bad girl. She fails to care and he fails to do anything. She is not here to please Eden; she is here for the One Being Sought and no one else. Rui will do just as little or just as much as she must in order to stay in Eden's good graces and no more and so she does not look at the reports.
Heike himself does not like where Eden is going. He has been there since it began; the organization is his child. Unfortunately it is a rebellious one and his paternal instinct is waning in rebellion. Heike does not like bad children but this one has grown out of control. For now he will play along because it is safer but he will not punish its employee, Rui, for her small act of agitation. Rui is never punished but Heike cannot leave his child just yet; there are many things left to do before he can apply discipline for its bad behavior.
And so the dance continues.
