Alastair (call me "Al") Montague prefers his dark room to, well, pretty much anything requiring social interaction. You will find out more about Al in "The Montague Twins and the Mystery of the Bony Fingers".
Pete questions everything, and before you can open your mouth to respond he's figured it out anyway. Pete has a tendency to fixate on problems whereas Al will shrug his shoulders and go with his gut.
Charlie spent most of her childhood traveling the continent with her mother, Shelly, a truck driver. She laughs easy, thinks hard, and has a strong commitment to political causes and fart jokes.
Fatherhood was never something David expected, and it came at the cost of his two best friends. After the death of Francis and Vanessa Montague, David volunteered to take in their twin boys, Al and Pete. After marrying Shelly, she and her daughter Charlie moved in, completing their family. While he once thought that children would disrupt his life of scholarly pursuit and solitude, he now realizes that his particular gaggle of teenage wards is the best thing that could have happened to him.
