Oh man, if theyI would be blown away. That would be a crazy and emotionally-heavy direction to take the show.
made the "rewrite history" line from the theme song into a storyline about going back in time to save Della (Donald's sister and the nephews' mom),
both "solve a mistery" what happened to Della and "rewrite history" save her. It would be a great direction for the show, but Della was not really a big character in Duck's lore, it was created to just justify Disney's line of thought that characters cannot have sons, so nephews were always introduced to bring kids to the stories (Mickey nephews, Daisy niece, Minie nieces, etc etc, the only exception I can think about is Max, but he is a recent creation. But that last scene cannot imply something else. This show is going to places.
