[Billy looks down at his work, obviously pleased. So it's all right. Ed's not having a problem anymore. That's almost enough payment on its own.]

Like I've said, you've already paid me. But...there might be one thing you can do for me.

[He brought his hand up, tapping his chin in thought.]

Could you send me any information about your world's technology? I know it's a big and broad request, and a single person's not likely to have much of it. But anything would be a delight to learn from.
