Only mine?

Don't lie to me, Seymour, I know you longed for it too.
What's wrong?

I thought you wanted the good part.
Hihihihi. Just kidding, I'm not ignorant of your desires. It's just that the Lady would never allow that kind of depravity within the confines of this play.
Yeah, I know, it's a shame, but actually, I just wanted to see how far you would go, how far I would go, and most importantly, how far the Lady would allow us to go. Sometimes one needs to test the boundaries. Every interaction allows me to understand more about you and about Her.
Didn't you want me to help my child fulfill their destiny of greatness? Do you really believe I am willing to hold their hand the way there? No, this is as much as I will do for them. Let that minion of yours deal with the babysitting.
Your child will never reach great heights with just your blood and the blessing of that vegetable, let alone become the "Unstoppable Mary Sue" you boast about. And pray tell, how can you expect me to recognize one as my child when I have no hand in their conception?
You know well that you have absolute power over me. At any moment, you can annihilate my will and transform me into
[The Bitter Scythe of Love, Death, and Chocolate], a tool designed to obliterate destiny. By becoming this weapon, I am eternally bonded to you, my beloved, ready to carve a path through the very fabric of fate. I love you so much that I am willing to give up myself for you.
My destiny can only be fulfilled through you.
But this child I carry is a different story.
They are innocent, without sin. They need protection until they are self-sufficient and capable of making their own choices. This is not babysitting. Every living creature needs this, and if it is lacking or if love is missing, they will seek it their entire life, ending up living an incomplete and tormented existence.
Your words almost make me think you don't consider them yours, but how is that possible?
Your blood flows in them. A child needs only love and guidance, support. Presence.
What our child will want from you is simply for you to be an example, to show them the way of villainy, to teach them how to conquer the world, make epic entrances, and verbally defeat heroes with the power of your monologues.
He takes your hand and places it on his belly.
He is visibly emotional, and you can feel the accelerated beating of three hearts in parallel, followed by a less strong but already present beat.
It is the miracle of life.
Your child.
the instruments inside the lab flicker to life, as television screens light up. Compared to the other wonders... these monitors seem quite mundane.
Haven't you noticed that she is watching us? And not just her. My Lucky Stars are shining in the sky as well.
There are a lot of things we can do for the child... decide their sex at birth, their hair color, eye color, physical appearance, eliminate any potential defects. But we can do so much more, give them the bloodline of gods, make them a pure Eldritch, remove all the problems that come with having a succubus in your family tree.. I've even made a breakthrough in my research after observing a certain someone, and we could trick reality into thinking of them as a fae. Yes, they can be eldritch and a fairy at the same time! How's that for being a Mary Sue? Hihihihi.
We can even alter their way of thinking. Hihihi. Though I doubt you'd ever decide to go along with that.
Ah, ultimately, the choice is yours, as you say. I only thought the child could be of use some way when I play the role of the VIllainess. If you wish to do nothing, then things will proceed as if nothing had happened.
Though I do hope you consider...
They will make their own choices, decide who to be, and determine their future.
Of all the crimes you might be willing to commit, eugenics surprises me the least.
But they don't need it.
After all, our DNA tells a story—yours, mine, and that of the dynasty from which I descend.
It is a precious tapestry that must be preserved. But our child will have not only their genetic code but also deities and Lucky Stars ready to illuminate their path. A diverse family of unique personalities, carrying an incredible baggage of memes. They will be the ones to sculpt the DNA of their soul.
We won't be alone in this, and neither will they.
When I said I wanted them to become the ultimate Mary Sue, that was just my aspiration as a mother. It's normal for a parent to have great desires and ambitions for their child. But these are only selfish wishes that should have nothing to do with the child.
I have realized that it is our flaws that make us truly alive, more than our virtues. It is imperfection that drives us to continually improve and to rebel against our destiny.
If you were not imperfect, perhaps I would not have fallen in love with you.
If I were not so imperfect, perhaps I would not have met you.
However, my choices are my own, and I take full responsibility for them.
Our child will make their own choices, with their own experiences and their own journey.
How do you envision them? We can dream about it together. We can discuss it, imagine it.
But ultimately, they will choose for themselves.
We can only love them and help them when they are in trouble.
There is one thing you can do with this equipment.
A selfishness we can allow ourselves.
Please check that they do not have debilitating genetic diseases or severe malformations.
If they do, please cure them.
