Here are some of my favourites:
"It is my duty to clean trash like you off this Island."
"Your age is over. It is time for a new age: OUR AGE!"
"Finally the salvation has come in the form of a kanohi mask."
"The Toa use masks to hide their ugly faces!"
Reidak: "Hakann, where you are going, I need you!"
Hakann: "Sorry, it's just business."
