It all came back to Ren Jidian, the last time he talked to Samael. Didn't he see that very same lizard?
And he said….
That he borrowed it from Valak to find Beelzebub.
So it's a lizard that can find objects and people. That means….
"How exactly did you get close to each other, Kallophon? I don't think you have ever told me that. After all, I have never heard anyone call you Gyllos." Ren Jidian asked. "Not even your fiance."
"You have a fiance?" Prince Cyrenos suddenly turned to him, his face turning sour.
"Bah, you know how it is. Arranged marriage and all that…. Your Highness."
"I see." The prince said, but he wasn't actually reacting that way because he was shocked or jealous.
He can read Ren Jidian's mind. And he could hear him starting to deduce their identity as Michael and Saklas. So….
[So we act sloppy, like we're trying to not be obvious but failing miserably.] He told Saklas in his mind.
