How we cite our quotes:
[Garret:] "Who rules you, nomads? Do you answer to someone's will besides your own? Are you free to choose your own path, or will the Volturi decide how you will live?" (37.168)
Garret tells the nomads that by taking the Volturi's side today, they're forfeiting power over their own lives and placing it in the hands of the Volturi.
