- Back from the Dead: Constantine, having sold his soul to a demon in Hell.
- Battle Couple: Sara and Ava.
- The Big Damn Kiss: But of course Ava and Sara get one.

- Continuity Snarl: Bordering on a Running Gag with Legends finales. The Fountain of Imperium being revived and staying on Earth is supposed to protect Earth from aliens.
