An interesting omission from what Nick has told his dad. He will boast about Judy's good deeds but not his own. The happy bun in the last panel was nice, showing her pride and contentment in having a loyal friend like Nick.Your use of color for certain purposes is always interesting. For example, the flashback with the violet hue to represent her telling the story.Yes, Nick was the first mammal in Zootopia that showed her that he believed in her and she had betrayed that trust so she owed it to him to make amends with him first. In hindsight it was exceedingly fortunate that Judy didn't go to Bogo, Bellwether or a Zootopia medical center with her knowledge about the Night Howlers because if she did then Bellwether would probably have become aware of it and might have had enough time to react to ensure Doug was not discovered and the connection to her remained hidden. Despite Bogo now having more faith in Judy's abilities I believe she wanted to have proof, not just a theory, before taking anything to him. Duke Weaselton had been caught stealing Night Howler bulbs and a reasonable guess would be that it was for whoever was making the predators go savage. To confirm this she needed to find Duke and the best mammal to help her do that, outside of the ZPD, was Nick. (It was almost as if someone had scripted it all out so it would all work out for the best.
