Or Regina could straight up ask what she planned to do with her. Which.. Belle really didn't have a course of action even planned. She didn't say as such, after all, even if this woman was dangerous, didn't she at least deserve to know the situation? Did anyone truly deserve to be left to the dangers of this place without proper understanding?
"Right now? I plan to answer questions and inform you of the entire situation if you still want the answers. Then we can go to the internet cafe to at least get in touch with someone who can help.

"So what course of action do you want to take?"
Was it dangerous? Perhaps. But right now she was more concerned on at least protecting the identity of those who were here from Regina's world. She clearly figured it out, if she had figured out Belle knew who she was. Nor was it like she was going to lie and pretend she didn't know. But she wasn't going to lie about the situation.
"What is going on here is important to know and I can answer those questions easily. But only if you want me to."
