Les Yay: Madoka, Mami and Homura have what can only be described as a Love Triangle, what with Mami outright saying she and Homura are in an epic struggle for Madoka's affections. Madoka herself also seems to have an unhealthy fixation with Mami's chest - to the point that she spent a whole conversation with Homura talking them up, while Homura had been talking about her rifles.
Homura: Wait... what are we talking about?
Madoka: Her... rifles, right?
Homura: Oh God, please have been talking about her rifles.
Homura: Oh my god. I'm leaving.
