"I wonder what it could be?"
"What do you think Lily?"
"No, it's probably not a lily. Oh. I see what you mean."

"Can I have a closer look?"
"OK, but make sure you don't drop it. I'm certain that Hook made this himself. Here you are."
"Oh, it reminds me of times gone by, Lily. I'm so glad Hook didn't throw us overboard when he found us stowing away on his ship."
Perhaps some secrets are best left bottled up for ever.
