Juliette Teeger, is the daughter of Adrian Monk's assistant, Natalie Teeger. When Monk and Natalie first met, she was eleven years old. She was named, at her father, Mitch's insistence, after her great aunt, Mitch's aunt Julie. Mitch admired his aunt for her bravery and her compassion, and also owed her for practically raising him from childhood. Natalie would later tell her daughter that the name suited her very well. She briefly went to the Sea of Tranquility exhibit at the science museum, and bought an aquarium from the gift shop for Mr. Henry, not realizing that the aquarium in question actually contained a priceless moon rock that was stolen by one of the tour guides at the museum.
