Simon Everett Grace is the older twin brother of Jared Grace, the younger brother to Mallory Grace and son of Helen and Richard Grace. He has an uncle Terrence too. He is somewhat nerdy but respects authority. He cares for animals and faeries greatly. Even to the extreme of housing and nurturing a Griffin. He is calm, shy, caring, and apparently a pacifist. Known for protecting his twin multiple times. Simon is one of the main characters in The Spiderwick Chronicles. Amongst the faeries, Simon is friends with Thimbletack, a Brownie, and a Hobgoblin, Hogsqueal, whom he rescues, as well as a Griffin, Byron, who in a way becomes his pet after he takes care of him and houses him. His enemies consist of Mulgarath the Ogre, Goblins that were Mulgarath's "helpers," and Red Cap, Leader of the Goblins. In the Film, he - along with Jared- are played by British actor Freddie Highmore. In the video game, Highmore also voices the twins.
