Billy snuggled down into her pillow, looking adorable against her Frozen quilt. Freddie sat in the chair next to her bed, and asked, "What story did you want tonight?"
Billy bit her lip in thought, then said, "A fairy story, Daddy."
"Okay, then. Now first… how do you keep one away?"
"Carry an iron nail in your pocket," Billy said promptly. "The fey can't stand cold iron."
"And if you think a fairy is making you lose your way?"
"Take off your clothes and put them back on inside out. Daddy… does that mean your underwear too?"
Freddie frowned. "Not sure, pumpkin. Back when people found these things out, they didn't really wear underwear – at least, nothing like we do. I'll check."
Given what Freddie now knew existed down in Mexico? He wasn't taking any chances, especially on a mythology as old as the Celts. His little girl was going to know how to protect herself against anything that might hurt her… especially things that most of the world thought didn't exist anymore.
