It's time to pay the bills......
This blipvert takes place in Toobworld, with this being the Walt Disney World of Earth Prime-Time, not the Trueniverse. And Regina established as being from the alternate TV dimension known as the Land of Fiction. (She also displays her serlinguistic skills......)
The Land of Fiction is NOT BookWorld, the popular term for the world in Jasper Fforde's novels about Tuesday Last. Once a character from Literature is visualized in the Television medium, it is no longer considered a native of BookWorld. Although they all share the same universe despite whichever book spawned them, character in BookWorld comes to life in the mind of the reader and could resemble anyone the reader's imagination summons. Once seen on the screen, the character is locked into that depiction.
