And Brubaker's reasoning of this decision on a Word Balloon interview two years ago was totally spot on. Bucky is NOT Captain America's Robin and never has been.
He said that? That's a good observation.
I just love how he handled it. It was done with incredible respect to both characters and was so careful not to destroy them.
I suppose if I knew a little more about the retcon that established that there were several different Caps taking the mantle while Steve Rogers was in the ice, it would make Bru's story even better.
