Did he say what happened to Della's husband? I mean, I don't think the firecracker killed him.
No info whatsoever on what happened to Hortense and Quackmore, either? It's weird to think of Donald as an orphan...
Also, now Scrooge gets along with his family, doesn't he? So, even assuming that Hortense is dead, why doesn't he at least try to make peace with Matilda?
