[ From the beginning Mami's worn this false face, the one she adopts when she sees Madoka again. It hurts to see her, it hurts to know that Kyouko and Sayaka are both moved on, but Madoka is still here, and it just hurts so much. It's almost enough to make Mami break down as soon as she sees that pink hair and those caring eyes. ]

Why are you...why are you apologizing..? [ Tears are welling up in her eyes, but she doesn't break down sobbing yet, because the confusion is too much. She doesn't know why Madoka would apologize. She has always been the perfect kouhai, the perfect friend, she doesn't know what Madoka thinks she did wrong. ]

It's not your fault...It's mine, I was selfish, I didn't want to be alone anymore..

[ Mami may be making things more confusing, but her tears are coming down again and all she can do is cry with her chin to her chest, her hands still held by Madoka. ]
I-I'm so sorry...
