Putting it elsewhere is not safe; at that time, Rone had already become the Headless Knight, and Austin, as the Dark Knight, with darkness and death being best friends, was undoubtedly a good choice.
The motive is established, the logic is coherent, and Grew is the most likely to be an undercover agent.
The least likely is the Executioner 'Wings of Winter' Xizor, who personally participated in the attack on Rone, which alone crowns him the top of the Hades rebellion party.
The last Judge, 'Spirit-eating Crow' Saine, according to Rone, is a creation of Aztemo; Saine came first, then Rone, so she counts as Rone's elder sister.
Saine is loyal, the number one supporter of Death; upon learning she was involved in the rebellion, even the mastermind, and attempted to seize Death's Divine Throne, Rone both deeply resented and disdained her.
This elder sister is not worth it!
"What, can't speak?" Omilos sneered sarcastically.
