I love how Dick's calling Bruce 'a big brother image' but they're totally being dad and son here. And how Bruce is a dad with a now empty nest, who copes by working harder and differently and moving to smaller digs.
Also, here's the same story, from Untold Legends of the Batman, by Len Wein and Jim Aparo.
Also, Dick likes Dr. Pepper.
