It's very obvious what the reveal is from the moment the curtains are mentioned, but I think that really helps the story that you've told. There's a sense of dread and finality that hangs over both Raina and Gerrick that neither can escape, and Raina's faltering denial fighting with her regret makes that thematic impossibility really work. I'd say the ending really seals the doom BECAUSE it's bloodless. She'll know Gerrick is out there, but nothing can ever happen.
