"Wait you actually become white? That was a joke about how if a Lantern master all the emotions he becomes white as well, in fact we call them a White Lantern. They are also the most powerful of all the Lanterns. It seems you have a bit in common with these rings, well I guess it's only fair I tell you about these rings, since you told me about yourself. There are seven normal types of Lanterns. Violet is love, indigo is compassion, blue is hope, green is willpower, yellow is fear, orange is greed and red... well red is the same as your red. That being said despite us using the emotion Red, we go around saving people, defending the innocent and punishing the guilty and no we don't kill or torture the guilty.
