While the Prince doesn’t know the Hatter from back “home,” David does have memories of reading stories about him. After putting two and two together — the hat that opened the portal belongs to him, after all — Charming tracks down Jefferson and appeals to something they have in common: Daughters they love and want back. Will it work, or is the Wonderland fella a lost cause?
