Ficdom: Evidenced when many readers expressed worry about the future of the comic when an unforeseen hitch made it necessary to move its post location.
Foe Yay: Kristoph and Kohal. If the author wasn't (supposedly) straight, you'd be forgiven for thinking that Kohal was an Author Avatar.
It is an Author Avatar, and a Self-Insert Fic for that matter. Sort of. Kohal was created by a friend of the author, and was used to give Kristoph an original prosecutor to lock horns with, as opposed to screwing with continuity by having him face Edgeworth or something.
Narm Charm: "I'm think I am be having the concussion now".
Although whether that counts as "Charm" or just regular Narm is arguable.
Of course, the same could be said of most Narm Charm.
And in a new comic "Have fun spending the rest of your life as a prison bitch".
