Warning: To avoid a completely spoiler-tagged blank page, all spoilers have been left unmarked. Be warned and tread carefully.
- Several in brutally quick succession at the end of Season 1: Rachel can stand, Rachel tries to kill Bam, Rachel was not chosen by the Tower, Bam was, Rachel hates Bam for stealing her dream. Headon is a Jerkass. Well, that last one isn't quite as much of a surprise by now, but still.
- Season 2, Chapter 18: Nia's betrayal and death.
- Season 2, Chapter 51: The Devil of The Right Arm has this back-to-back in increasing 'wham-ness'. Apple and Michael are traitors, Gyetang is dead, Dan turns out to not be such a bad guy after all, Rachel is finally confirmed as flat-out evil and/or insane, and Khun is has gone missing. Possibly one of the biggest Wham Episodes in the entire series.
- Season 2, Chapter 65: Viole wipes out two of Shibisu’s teammates easily with his new "Thorn" power, Rak shoots up Khun and Wangnan, Traveller reveals Viole's identity to Endorsi, and Viole outright says that he's lost the will to live.
- Season 2, Chapter 84: After Team Mad Dog seemingly allies with Viole to help him rebel against FUG, not a chapter later it reveals that all of them, Baragav included, are loyal dogs to FUG and the ENTIRE act of running from and despising FUG was solely to lure Viole/Bam into a trap, and they show no remorse in mercilessly trying to kill Nobic. Also, the true Thorn is the leftovers from when Enryu killed a Guardian, and to revive it as a proper weapon again FUG has been working on implanting a proper host with a demon that can resurrect its power. As if THAT wasn't enough, domo-kun cap boy Beta reveals to Viole that many Elders and members of FUG despise the idea of the new junior member obtaining what is basically one of the most powerful known weapons to exist, and have plans of their own, and cements that FUG and the scientists of the Workshop have been working together the entire time snatching up humans from the middle area of the Tower in secret for experiments.
- Season 2, Chapter 90: Hwaryun was disguised as Yuto, the real Yuto's purpose was to deliver the fake Thorn and gain the Elders' and Reflejo's trust. The fake Thorn is a container for the real Thorn which absorbed the Thorn when Viole was in close proximity for a good while. Viole is now free.
- Season 2 Chapters 144-148: Bam meets Rachel again after almost a decade and Rachel coldly shoots him down when he asked why she did what she did. Bam can't comprehend what she's saying, showing some stalker-like tendencies, and then flips out. Also we see Rachel might not be as "evil" as everyone thought from the way she initially reacted upon seeing Bam again.
- Season 2 Chapter 227: Wangnan gets captured by Rachel after getting brutally beaten up by Cassano, Akraptor is killed by Rachel, and Prince gets devoured by Hoaqin. This is shortly after a chapter where Ehwa and Rak are thought to have been killed by getting caught in the crossfire of a fight between two High Rankers.
- Season 2 Chapter 240: is a huge one. We learn about just who Bam is and where he came from, about Jahad's whims after stopping his climb and also the purpose of Enryu and his reason for killing the Guardian of the 43rd Floor.
