Killertongue is the nickname that Capricorn's mother, Mortola, gave Mortimer. This is because Mo had read Capricorn's murderer servant, The Shadow, out of the book Inkheart. He then turned the shadow on Capricorn and his men and killed him. Mortola hated Mo very much afterwards, and forced him into the Inkworld, where Mortola discovers that her son, Capricorn, is dead. Mortola then hurls the insult at him: "Silvertongue! Killertongue suits you better!"
