"Um, I think there's a few charges of the spell in here, but I don't think it's enough to use on all the people here.." But at least enough to use one on herself too. And since he's telling her to do so, Madoka is quick to obediently do so, even if it's a little harder to angle it in such a way that she can cast the spell on herself.

But after a moment or two she manages to do it - obviously so too, since Madoka looks equally surprised when she can see the truth of the city around them. It's such a stark contrast with how it looked only a moment ago..

"No way, the people here have been living in such a place all along..?"
