Origin
His father was a mean drunk, who beat his wife and son whenever he was drunk. Danson often hid in his closet to escape from his father.
As an adult, Danson became a retriever. Someone who hunted down missing A.I. robots and brought them back to their owners.
He is a regular customer of A.I. prostitute Lacy, knowing he can be as rough as he wants with her. Often resulting in Lacy needing repairs after his visit.
For her birthday, Danson gave Lacy a snowglobe with maquette of the Swiss Alps in it.
