Trivia

 * This episode was previously titled "Heart of the Fire Kingdom".
 * According to Adam Muto, "Incendium" features "some Rebecca Sugar songs", and several new characters.
 * Incendium means "fire" or "burning" in Latin.
 * This is the second episode with its name in Latin. The first was "Morituri Te Salutamus."
 * The "wad of hair" from "To Cut a Woman's Hair" and "What Was Missing" returns once again.
 * In the preview, Ricardio's voice (George Takei) seems to be narrating, which is most likely because the episode premieres the day before Valentines day.
 * This episode demonstrates that Jake can play acoustic guitar, first shown in the episode "Susan Strong".
 * This is Adam Muto's and Rebecca Sugar's last episode as a team (see promo art). As from this episode, Adam Muto was promoted to creative director and Rebecca Sugar will work together with Cole Sanchez.
 * Even though the episode airs at 7:30 PM, the promo art says it airs at 8:00, a mistake made because of a habit back when episodes aired at 8 PM.
 * Rebecca Sugar said it's the episode when she could finally make Finn cry, altrough he cried briefly before in "Jake vs. Me-Mow".
