While sneaking away from his sister (by again flying out a window), Cid notices Beethoven’s Moonlight Sonata being played in a concert hall. It’s Epsilon at the keys. Like Gamma and Beta, she’s using knowledge from Cid’s world to advance her position in this one. He doesn’t mind, and even compliments her figure, because he loves the Moonlight Sonata. And why the hell wouldn’t he? It’s the perfect theme song for Shadow.
He asks Epsilon about Rose’s whereabouts, but all she knows is that she is in the underground labyrinth. That’s all Cid needs to know. Alexia is already leading Beta down there, the former by now completely unconvinced that “Natsume” is a weakling. Alexia doesn’t know how fortunate she is that Beta is capable, because they’re heading into a totally unknown and potentially fatal situation.
When an exhausted and bloodied Rose catches her breath, we finally see what she encountered when she met with her father and Lord Perv. The king was clearly not in his right mind, and he and all of the assembled nobles and courtiers were under Perv’s control. Rose lashed out with violence, but now regrets that decision as a princess shouldn’t be so reckless and shortsighted (though considering that’s Alexia to a T, maybe they should?)
The nasty wound on Rose’s chest wasn’t caused by her pursuers; rather it is the early effects of possession; before long she’ll be consumed like Alpha & Co. were before they were freed from their curses by Cid. Just as Cid wishes he could have been there to see Rose go all “rock-n-roll”, Rose wishes she could get rid of Perv and his ilk, marry Cid, and live happily ever after. Now she’s not even sure how much longer she’ll live, period.
Throughout her monologue, which is spoken aloud, I kept thinking Cid would emerge from the shadows to tell her he still believes in her, still has her back. Of course that’s ridiculous; Cid would never act like that. Instead of emerging from the shadows, he appears before her in disguise as Shadow, playing Moonlight Sonata on the piano he borrowed from the concert hall. A gorgeous moonlike light suffuses the hall, and thousands of white feathers fall, all adding to the theatricality. Cid is killin’ it here.
Once the sonata ends, he stands up and asks Rose if she’s going to give up or keep going. Rose isn’t sure how. Shadow tells her he’ll give her the power to do anything and everything she needs and wants to do. With few other options, Rose accepts, and Shadow not only extracts the curse, but imbues her with power comparable to the Seven Shades.
Shadow doesn’t stick around, leaving a single black feather on the piano keys, because he doesn’t have to. Diabolos assassins arrive, but the newly supercharged Rose turns them all into red mist with a single slash of her sword. With this power, perhaps she truly can save her father, her kingdom, and all the other nations threatened by the Cult.
When she encounters Alexia and Beta, the former demands to know what’s going on, but Rose won’t tell her. She doesn’t want Alexia to get dragged into it, and telling her will do that. Alexia won’t take no for an answer, and starts a fight with Rose. While she fights better than Rose expected, she’s obviously no match for her.
Rose leaves an unconscious Alexia with Beta, who doesn’t offer any resistance and even expresses her support for Rose’s future ventures. Their alliance may now be shattered, but Beta suspects they’ll meet again. Beta is hardly one to question Lord Shadow’s actions—if he bestowed upon Rose the same power as her and the other Shades, he must’ve had a good reason.
