A technical note. That would do it. Something that he and Cobb could share together. Co-authoring a new paper, maybe. Wow. A great idea, that would be fantastic. After all, the guy had practically invited Van to help him. He could breathe fresh life into something that Cobb had left on the side of the road. It would be like a Festschrift tribute. That should be easy. There was so much there to choose from.
