David has to read the note three times before the words register. Callie and Alex? The thought makes him slightly sick and he is not even sure why.

He takes the car without asking. He could ask, but Alan would want to know where he was going. Alan would see that something was wrong and he would want an explanation. He wouldn't push for one. But he would ask. And David would rather that he wouldn't ask.

So he takes the car and drives to Clay's. He knocks on the door. No answer. So he sits in the car and waits. Nothing seems as bad inside the car.
