Was it so cruel and unfair that mami died when she was becoming happy and more confident in episode 3 when madoka said she would fight with mami?

it was cruel, but i kinda saw it coming

Whatever. I knew it would happen sooner or later. She was foolish, carin' so much for other people anyways. If she had come to her senses quick enough, that wouldn't have happened.

Yes, truly. That's why Madoka Kaname is crying 4 times in episode 4. 3 out of the 4 times make me sad. The saddest one is the 3rd time Madoka's crying. Her eyes swallow from crying. This can explain Madoka is crying so hard inside Mami's apartment. I can feel the sadness of Madoka.
