Cartoon-verse: the reveal in O is for Obedience that Julian and the Mage were lovers who had a son (Caleb) together, and then that the Mage was actually Nerissa in disguise.
- It began in F is for Facades, when the Mage tells Julian:
Mage: He has a fine father.
Julian: And a fine mother as well.
*cue the two of them smiling at each other*
- And then, in N is for Narcissist, when Luba reveals that the Mage was not the Mage at all, there is a close-up to Julian's downcast face.
