Yeah. Kei looked really down at the end of the ep. But on the other hand, it has seemed like the constant competition with Kei is currently the only think Hikari is living for, so it makes a little sense she has an automatic defense mechanism for anything that could disrupt that view of the world. Still, she is incredibly thickheaded.

It's also safe to say with this episode this series waved goodbye to any realism it might have once had...
