Prince John is the younger brother of King Richard, who spent egregious amounts of time trying to usurp his brother's throne. Though he is referenced often as a villainous offscreen character, masterminding all the schemes to kill Richard, throughout the series, he does not appear in person until he arrives in Nottingham in the episode "Do You Love Me?".
Prince John seems to be affectionate of Isabella. Both of the real Prince John's wives were called Isabella (though the first marriage was annulled).
- "Do You Love Me?" (first appearance in person)
