How we cite our quotes: (Chapter.Paragraph)
Quote #1
Artemis was the closest thing Butler had to a friend, and Butler was the closest Artemis had to a father, albeit one who obeyed orders. (1.129)
A lot of Artemis's personality obviously comes from his father and his disappearance, but considering that Butler's been around Artemis his whole life, it seems like Butler's probably influenced him too.
Quote #2
People said he was a chip off the old block. They were wrong. Master Artemis was a brand new block, the likes of which had never been seen before. (1.138)
What's interesting here is that Butler is the only one who could actually say this and we would believe him. He's the only one in the story who knows exactly what Artemis Fowl Jr. and Sr. are/were like.
Quote #3
Artemis stepped into the shadowy folds of his mother's robe. She smelled perfumed, like petals in water. But her arms were cold and weak. (2.34)
Watch for the reappearance of the perfume later in the story when his mother's madness is cured. Scents are a big part of how animals recognize family, and it's a curiously primal detail to have Artemis so focused on his mother's perfume, like it's the only stable thing about her.
