Trivia

• "Kerttu" is the Finnish form of "Gertrude" and means "spear of strength."
• While in the Philippines Kiera Cass joked about the next generation and came up with "Gertrude, the nerdy princess." Since Kerttu's name is the Finnish form of "Gertrude," this suggests that Kerttu is the girl she was joking about.
• Pronounced "Care-two"
