Gosh, my heart just absolutely broke for Usagi seeing her clutch that star locket alone in her dark room; it's like she was desperately trying to hold onto any piece of what they had. I totally got why she'd try to change her hair, just wanting to escape herself and her pain, but of course the Dark Kingdom had to mess that up too. Then, for Mamoru to treat her like a complete stranger at the end? Ugh, that was just brutal and unfair after everything she's been through.
