How Scarab's punishment for killing Rapses wasn't to be executed but to be entombed alive. While the series doesn't reveal all the details, it doesn't shy away from what a heinous act this was. Before Scarab's sealed in, Amenhotep even taunts him:
The Literal Cliffhanger scene where Scarab is looking down at Ja-Kal (think Lion King), then Presley heroically pushes Scarab from behind off the cliff and pulls Ja-Kal up... seems a lot weirder when you remember both Ja-Kal and Scarab can fly.
