Yes, and a bit of the history of Nemesis!

"...heh!" Sothis suddenly started giggling, and Byleth paused, and looked towards her along with Rhea.

"...there a joke I'm missing here?" Byleth asked a bit curiously, wondering what had Sothis amused.

She got her laughing under control. "Well, Master, it's just... it occured to me... now you own me, body, heart and soul, but in an entirely different way than before..."

Byleth blinked, wondering what she meant, before it clicked. As his Sex Genie, that was a bit more metaphorical, but considering he essentially had her heart in his chest in the form of the Crest Stone, her soul living rent free in his head, and now... he basically had her remains in his hands. "...did you have to call attention to the fact that I'm basically now going to be wielding your corpse?" he asked her.

She shrugged. "I mean, that was once my body, but not so much anymore. Now I can just make myself a new solid form whenever I want. Not like I'm using those old bones anymore, and if they still got some of my power, might as well use them, right?" She then paused. "Although, considering that I was essentially dead... does our relationship count as necrophi-"

"And we're done with that train of thought!" Byleth immediately cut her off, Rhea choking on her spit. "What did I tell you about discussing our situation?"

"What? I'm not acting like an outright slut, nor am I trying to ask Rhea to join the harem right now!" Sothis pouted. "Just stating facts!"

As Byleth face palmed, Rhea managed a weak chuckle. "I am so sorry for her, Professor... As much as I love my mother, she never did have the best... Impulse control."

"...so that's not all the genie thing?" Byleth side eyed Sothis as he asked the question, causing her to puff out her cheeks immaturely. "Guess you don't have that excuse anymore..."

"Regardless, I should probably ensure you are at least informed about the official history of Nemesis in case it comes up," Rhea started. Byleth and Sothis blinked at that.

"Official history? As in, you lied to the populace in some way about him?" Sothis questioned, shaking her head.

"I had a very good reason for it, Mother," Rhea replied defensively. "Back then, I had spread the story that he was granted his abilities, the Sword of the Creator, and the Crest of Flames by you in order to defeat wicked gods, which he succeeded in. Only to then become corrupt due to his power, and force me to destroy him."

Byleth looked at Rhea in confusion. "Why tell that kind of lie?" he asked her.

Rhea grimaced. "I did not want the people to know how Nemesis actually got his power. The idea of the Goddess being dead would have terrified the people... furthermore, if it got out any further that Crests, and powerful weapons could be obtained from our blood, hearts and bones, then..."

"...that would risk the safety of you and your kin," Sothis sighed, begrudgingly aceepting that that was a pretty damn good reason.

"Exactly, Mother. There were other reasons, but those were the main ones," Rhea nodded.
