I love the complication of the kids in the characters' lives. I love that these two people are very capable in all these ways. They're so trained. They're kind of deadly. They're smart and vicious at times, but I love that they're undone by a teenager, like we all are. We're all incensed and undone by the ungratefulness of a child, and I love that it matters so greatly to them, in a way that it matters to every parent. Teenagers are going to do that no matter where you live or who you are.
