She doesn't really have a choice though, does she? Madoka knows what she'll have to do when she gets home. And while she isn't entirely sure how it'll end, whether it's with her changing or even just dying, she knows that her wish will mean that she'll never be able to return to her normal life.

And so, if people forget her because she's been stuck here for such a long time, away from home.. It just feels easier.

It's something she can't change, anyway.

But somewhere between Ken's earnest words and Wormmon's wibbling, Madoka feels cruel trying to subject them to it. They're not from her world. They shouldn't be burdened with any of this. It's something she should just bury deep within her own heart, carry with her until the day comes that she can go back home and carry out her duty.

"Ah.. I'm sorry." So she just tries her best to smile at the two of them right now. "I didn't mean to make you worry. Don't worry, it's not like I'm going to make you two forget about me!" (Until the world does it for her, ssh...)

"I was just thinking a little about things, that's all..!"
