So this probably falls into the 'not much of a choice' category, Bigby figures. Just the woman's emotions working faster than her brain-to-mouth filter did. After all, they just met, so it surely can't be the trusted angle.

Bigby nods a little bit as he takes it in. There's a moment of consideration about his own situation. He's not supposed to give away their secret, sure, but.. that's to mundies.

She's clearly not a mundy.

Maybe it'll make them even again, a secret for a secret. And it's not like Bigby has had a hard time here, keeping the truth only close to his own chest, not having people to share it with the way he did back home.

"Well, if it helps, I have powers too." If you'd call them that. Bigby doesn't really think of them that way, but he's well aware that other people would. That they wouldn't see them as being as natural as he himself does.

He pauses, then slowly exhales.

"You've ever heard about stories? Fairytales?" That's what the mundies call them, right? "Either back home, or in those other worlds?"
