Fiona uses pushpins to hold notes to the Border House noticeboard. April took the pin along with a pink note about a lost ring, which turned out to be hers. She used it to wind the the pocket watch Cortez gave to Westhouse, who in turn gave it to her.
She later used the pin to prick her finger when she needed blood to create the Gold Pearl.
Obtained from the Border House's living room noticeboard.
