- It is hinted that Armaros might be still alive, since a scene after the credits and after Lucifel's lines of dialog, shows the Water Nephilim, Armaros's son, swimming peacefully in the abyss.
- The manga states Armaros is unique among the Grigori since he was not a Watcher. He simply befriended Enoch and became fascinated about humans.
