Trivia

 * The name "Ingrid" is from the Old Norse name "Ingríðr", which means "Ing is beautiful". Ing is the name of an obscure old Germanic fertility god, and could possibly mean "ancestor".
 * According to herself, she has hundreds of mirrors. Some of them can be seen decorating the walls in her ice cream shop.
 * Her adopted alias in Storybrooke is Sarah Fisher. During the first curse, there was a Storybrooke business called Sara's Ice Cream located right next to Mr. Gold's pawnshop. It was still present when the curse was undone. Yet, this other ice cream shop did not belong to the Snow Queen.
