Massie was the only member whose name didn't have an "ahnna" sound, making her the odd one out of the clique.
The Ahnnabees were introduced in The Clique's prequel novel "Charmed and Dangerous: The Rise of the Pretty Committee.
Massie originally wanted to be in a clique called LMNOP, but couldn't join because there was already a person whose name starts with an "M" in the clique.
While a member of the Ahnnabees, Massie always thought that she didn't fit in because Ahnna never took her ideas into consideration and wasn't very friendly towards her.
After Massie meets Dylan Marvil, Alicia Rivera and Kristen Gregory at Merri-Lee Marvil's New Year's Yves Party, she ditches the Ahnnabees, transfers to Octavian Country Day and the Pretty Committee is formed.
