- Breather Episode: Explicitly called this by
Word of God, and for the most part things are rather light as the heroes celebrate their recent victories. Then Megatron makes a reappearance. - Cardboard Prison: It only took around a week for Soundwave and Shockwave to free Megatron.

- Held Gaze: Kallen and Lelouch have one after going over the plethora of good news and developments with the Decepticons' disarray and formation of the UFN. When an amnesiac Cera ask what she should do next, the pair, who are on cloud nine, absentmindedly suggest she sing and dance with her clothes inverted. Kallen and Lelouch break out of their trance when Cera verbally complies and the two quickly stop Cera as she began undressing.
- Internal Reveal: Marianne reveals to her children that she's still alive in Anya’s body.

- No Body Left Behind: When V.V. was extracted from Nemesis Prime, and was found to be dead due to Megatron taking his code from him, the Black Knights groundbridged his body to the center of the Earth in the hopes that the extreme temperatures would disintegrate his body... though given what exactly lies at the center of the Earth, this trope might not be in effect.
- Relationship Upgrade: After being implied during the Iacon Relic hunt, it's confirmed here that Lelouch and Kallen have more or less started a romantic relationship.

- Wham Episode: After the majority of the chapter appears to be a Breather Episode, the ending has Megatron suddenly return, having been freed from the Shadowzone by Soundwave and Shockwave using an artificial Thought Elevator. Worse, it's confirmed that he stole V.V.'s Code, making him immortal and just needing Cera's Code to enact Neo-Ragnarök.
