The conventional reading of Miranda in The Devil Wears Prada 2 is that she has softened. Time has done its work. Power has mellowed her. This reading is comfortable and inaccurate. What is interesting about Miranda in the second film is not that she has aged into kindness. It is that she has retained the option, after all this time, to be questioned and to be moved. That option is precisely what most people in long-held positions lose, and they lose it without noticing.

Aging in a role does not produce growth. It usually produces certainty. The longer someone holds a position, the more they accumulate evidence that their judgment is reliable, the more rarely anyone tells them otherwise, and the more expensive it becomes to revise. People around them learn what gets a response and what gets a silence, and adjust. The information narrows. The conclusions firm up. From the inside it feels like wisdom. From the outside it looks like a closed circuit.

This is the default trajectory, and it gets stronger with status, not weaker. The cost of being wrong is highest for the person who has been right the longest. So the people who most need to keep growing are the people for whom growing has become the most expensive.

Experience accumulates by default. Growth does not.

What Miranda does, imperfectly, in the second film is a different kind of work. She lets a younger person contribute to her thinking without treating it as a competition. She holds her edge but loosens the moat around it. She hangs up her own coat. The coat is not the point. The point is what hanging it up signals about whether every person in the room still needs to confirm her position before she can begin her day. People who have grown in their role have released that requirement. People who have only aged have not, and usually cannot.

Growing in a role is not the same as becoming nicer. Some of the most generous people in organizations are immovable. Growth shows up in something quieter and harder to perform: a willingness to be told something that changes the picture, and to actually let the picture change. It does not require giving up authority. It does not require softness. It requires staying reachable, which is closer to a discipline than to a temperament.

Most people do not grow in their roles. They thicken. The work that would keep them moving stops being asked of them, and they stop asking it of themselves, and after long enough the question of growth simply leaves the room. The exception is rare and not automatic. When you see it, it is worth naming, because it is not what time does. It is what someone keeps choosing to do with the time.

Second of three readings of The Devil Wears Prada 2. The first is on the conversation neither side starts. The third turns the question back on the viewer.
