Jack Howl

Epel Felmier
 * Calls him Monsieur Crabapple
 * While, in English, "crabapple" is a combination of the words "crab" and "apple," in Japanese, "crabapple" is hime-ringo&mdash; a combination of the words "princess" (hime) and "apple" (ringo). This is possibly the writer referencing Snow White, given she's also a princess associated with apples.
