"Let's finish this fight." - John-117 arriving on a battlefield during the Consortium War

One thing that was noted is that John tends to keep his word when he gives it to someone. John is also known to show an exceptional care for soldiers under his command, a trait he and IceBite seem to share. He has a light paternal instinct for Zack, as the latter is the son of two other Spartan-IIs.
