Suzaku blinked, from Enki's mentioning of it when they had first met, speaking of how hated violence but if his king ordered it he would have to kill Suzaku had assumed that Shōryū did so. After all if he had the ability to make Enki obey him he would use that. Even though it was obvious Enki was happy to go along with Shōryū anyways there were always going to be moments, especially since Enki hated violence, that they clashed and if Shōryū had the means to make Enki do as he said...

It didn't make sense any other way, that would be like Lelouch not using his Geass, any of those with Geass not using the powers given to them to control those around him.

Though on second thought Lelouch had never used his Geass on Suzaku, Suzaku's mind went fuzzy and he frowned, but he hadn't...

"He's a king and you have to do as he says, but he has never ordered you to kill?" Suzaku sounded as incredulous as he felt.
