[Byleth was hesitant, unsure if Claude was trying to bait him into saying more than he should. But at this point, if Byleth couldn't trust Claude, then he couldn't trust anyone here.]

...I know that I have a Crest Stone implanted into my chest, and that is what's functioning as my heart. I also possess the Crest of Flames, passed down to me from my mother, Sitri. Jeralt faked my death as a baby, so that he could take me away from Garreg Mach and Rhea, because he didn't trust her. We've avoided the Church ever since.

[Safe, easy answers. There was a pause, one where Byleth gave Claude a long stare, weighing his words.]

I also know that I'm not entirely human. [His voice is quieter here.] Not even Jeralt could accurately say what... I am, exactly.

[Jeralt had admitted his ignorance when finally telling him about everything - including his own long lifespan and convoluted history with Rhea. Jeralt had known what Sitri was - a vessel, created by Rhea, but what that entailed... Rhea was skilled at blood magic, transfusing it, creating homunculi, and it was likely Sitri shared Rhea's blood and flesh. Jeralt didn't know, could only speculate.

But it didn't matter, Jeralt had said, at the end of the day, Byleth was himself, and that's all that mattered: "Even if you sprouted wings and turned into a Divine Beast right in front of me, you'd still be my kid, got it?" Byleth had believed him - still did.]

I'm also the vessel for Sothis. That's... all I'm aware of. I think.
