It was more than a lot but she wasn't going to say anything on else on the matter. All throughout Belle's description of what the Seals of Hell were Regina kept looking her up and down. This girl was obviously not her Belle as she hadn't known who she was when they first happened upon one another. Nevertheless hearing the name Belle brought back memories of the girl she'd locked up in her dungeon and in the asylum in Storybrooke.
"Different worlds?" She was no stranger to the concept of different worlds. In fairytale land she'd used Jefferson to take her to Wonderland. A land very different than her own. The hat capable of traveling to different lands but not without its own set of rules. The same amount of people who went through the hat must come back through. A rule she had once used to her advantage trapping Jefferson in Wonderland until she cast the curse pulling him through with everyone else. Storybrooke had also been a different land than her own. A land without magic and happy endings. A land where she would reign victorious over everyone. Until even that had failed. Somehow she figured that the "different worlds" that Belle was referring to had nothing to do with what she was thinking of. It was something entirely different.
