Aurora being cursed twice, even though there’s two different timelines now, I don’t think that makes sense either. I think Aurora was only cursed once.
Actually. We can pretty confidently say that she was only cursed once, right? The Red Room. She was terrified of it, as if she had never been there before. If she had been cursed twice, she would know what to expect the second time ’round.
Part of the conversation between Snow and Aurora in Tallahassee
MMB: It’s okay. It’s over now. These nightmares… They will fade away. I promise.
Aurora: Did they for you?
MMB: Yeah. Come on. Come on. I’ll sit with you until you fall back asleep. Who else do I have to take care of?
Aurora has clearly never been to the Red Room because she doesn’t know that the nightmares never fade (recall Snow’s face when she says the last line…)
