"I can hear them," she murmurs. "Not words, but voices. They are not currently fleeing."
"I'd be really surprised if a wizard came out to meet you. Maybe Calemar's mom, though."
Eventually, a woman of some sort - whether she is Calemar's mother or not is not immediately obvious - emerges from the cave with her hands held up palms-front and a terrified expression on her face.
"Please don't hurt me. Us, please don't hurt us," blurts the woman.
"I do not plan to hurt any of you," says Sherlock, "unless you try to hurt me first, which I don't expect is likely. Perhaps you would like to explain what you are doing in my forest?"
"We thought it'd be safe as long as the royal family didn't find us," says the woman, looking like she'd like to wring her hands but would like to remain obviously unarmed even more.
"And what do you get out of living in a cave in the Enchanted Forest that is worth the risk that we might?"
"I see," says Sherlock. "In that case, provided your presence is not destructive, you may stay here under the same protection as any other resident of the forest."
"I don't know anything about that," demurs the woman, "but we're not hurting anyone..."
"The forest magic is my primary concern," says Sherlock. She addresses the woman. "Please allow the small child to ask squirrels the way home if he is lost again."
"Oh, you've already found us, the squirrels themselves don't matter," says the woman with a shaky laugh.
"Do you want me to cruise through the cave and make sure they're not up to anything magically nefarious?" Bella murmurs to Sherlock.
"There are some wisps coming in, but it's unused residue, not uprooted useful magic. The same sort of stuff my marble grabs," Bella reports when she's retrieved the end of her thread from Tony.
"...You'll just leave us be?" asks the woman suspiciously. "Are you going to tell the Queen?"
