It doesn't matter where she is. She could be waiting for the subway. She might be out in front of the Louvre, where the glass pyramid, carefully staying out of the way of skateboarders. Wherever there is a flat surface (or even a not-so-flat one), River
is dancing.
It's been a hectic few days. Finding herself in an entirely new place, without her brother. Without her crew. But dancing calms her mind. And so she moves her body to whatever song is in her head, letting the steps soothe her.
