Madoka shakes her head - pretty quickly after Persephone says that, like it's a near-instinctive reaction. Something the girl doesn't even have to think about.

"I can't."

Okay, technically she can. It'd be as easy as just pressing a button on her SCA, and she'd be right back in the train. But that's not the kind of can Madoka is talking about.

"I-- I want to help. But I.. I don't know how.." And it feels a little shameful at the same time, everything she's doing here. If she wasn't clinging to Persephone, the other could probably do more. As things are, she's just getting in the way, isn't she?

But Madoka can't help it. Clinging to Persephone like this is the first time this morning she has felt safe, and that makes it hard to let go. The other is like a beacon in the middle of a storm at sea.
