Amid the power and the glory of Breaking Bad came the moment in season four when Walter White at last articulated to Skylar, his panicking wife, his transformation from terminally ill middle-aged chemistry teacher to badass drug kingpin.
Are we in danger? She asks him. Are you going to answer a knock at the door and get shot?
"I'm not in danger, Skylar..." Walt rages at the end of one of TV's great monologues. "I am the danger... I am the one who knocks."
In the long-running power play that is the ECB versus Kevin Pietersen, the same kind of moment has come. It's a delicate moment, a complex situation, and no-one involved seems to know the whole story. Colin Graves has subtly manourvred events so that the argument will at least be settled out on the pitch, where it should always have been resolved.
With a single phone call to Pietersen, he has softened an official position that had helped to turn the ECB into a self-described 'toxic brand'. He has shown Paul Downton how he should have dealt with the situation, and put on notice a chief selector who appears to have let the modern game pass him by. This is a nuanced intelligence at work; one that has been missing throughout the gaff-prone year just gone.
There is a notion that Pietersen was looking for the chance to ditch his 'disappointing' $205,000 IPL contract, but I doubt that. Few are the cricketers who can afford disappointment on that scale, and Pietersen is revered in India. He is playing for Surrey because he is the one who knocks. The path is clear now. Score enough runs and the sheer force of them will open the door.
Pietersen has played something like twelve first-class games in eight years. He averages 98 in that time. He will knock again. How that will sound for Downton and Whitaker depends on their performance now. He won't get back into a winning team, at least not at first, but whether England are winning or not depends a lot on the choices they make.
There's a fairness to it which reflects the meritocracy that sport should be.
