Ren Jidian was the only one who witnessed what happened, but he wasn't the only one aware. There was still the former Archon of Desire and now God of Wine who had long sensed the desires for rebellion by the Archons.
Dionysus also doesn't need Persephone to tell him that Ren Jidian watched what happened.
Because he was already expecting him to do so.
Actually, that had been orchestrated all the way to the Aeons meeting again in the agora. But Dionysus couldn't take all the credit. The mastermind was of course, the former Archon of Deceit and now the cunning orator.
It was Saklas' idea to lure Ren Jidian to see them, way before they laced the pomegranate wine with Aphrodite's hair.
"This is our perfect chance. We learn Gabriel's plans, and we actively stop it by having the Aeon know the truth. Two birds in one stone."
