Danny was one of the regulars at the Clock, a pub and bar very nice. Danny usually visits the pub after he ends with his work, usually in night shift.
In the Watch story, Danny is an analog of the civil identity of the character of the Nite Owl, who instead of be a retired superhero with owls icons, Danny is just a working man always working in the night, helping people as a nurse. He is in a intermitent relationship with Lauren.
