Ok, let me explain why Killian Jones becoming deputy is my most FAVORITE headcanon to become true.
This guy ditched the Royal Navy and became a pirate, because their corrupt king caused his brother’s death. He saw the Navy as a way to become an honorable man, but he decided to pursue something more honorable than serving a corrupt king. (”For at least among thieves, there is honor!”)
Killian becoming deputy just makes the Storybrooke Police Department more of a family business since Emma and Charming are already in it. Kind of cements his place in the family and town. Not that he already wasn’t, of course, but becoming deputy makes him even more a part of the community.
It’s also him coming full-circle. Taking up a mantle as someone to protect the realm from harm of villains. It’s just so wonderful and beautiful for his character development and I’m just overwhelmed at what beautiful poetry this is :D
And let’s face it; guy needs a day job LOL
