The first time Eames sees Arthur, he does a double take because Eames has never met an American twenty-one year so well put together. Everything from his perfectly gelled hair to his shined shoes tells Eames three facts about Arthur.
One, he likes order in his life, two he is clearly gay, and three he's lonely. So Eames intends to take these truths about Arthur and put ruffles in his life.
Why? Because in Arthur Eames sees everything he is not, everything he's missing, everything he needs in his life, and because he's falling in love and he wants forever.
