I feel like if MC (or atleast delicate innocence MC) decides to have a child with Pierrot it would be purely to prevent him from khs when she eventually passes.
Dont get me wrong, after years of being together they've been through so much, and they've both grown, but Pierrot's impulsivity and big feelings are just part of who he is and there is simply no changing that, nor does she want to.
Pierrot likes to dream and sigh about their forever together, and MC loves the twinkle in his golden eyes whenever he does, but as time passes it became a source of anxiety to her, because she knew that when the time comes he's not going to accept it, nor move on.
She tried to bring it up multiple times, but everytime she does he either deflect or shuts her down, so eventually she gave up and decided to go about it differently.
If she can't stay with him in his forever, maybe a piece of her can.
Jester wasn't as hard to convince as she initially thought, he's always been a being driven by logic and practicality. He understood.
And where Jester is, Ticket taker follows, so he didn't need much convincing from her part.
Doctor was against it at first, warning that carrying a hybrid child would be a heavy task for a human body with a 50/50 chance of surviving the delivery, but the promise of documenting such a rare thing was too perfect to pass on.
Harlequin wasn't pleased the slightest. He'd argue that it was simply not true, that she was overthinking per usual as his smile remained just as wide, but the way his teasing words turned borderline hurtful suggested otherwise. He didn't avoid her, God no, but his presence that used to illicit laughter and mischief, turned into something cold and sorrowful. She pretended not to notice.
Pierrot of course when presented with the positive pregnancy test was ecstatic, he's always dreamed of starting a family with her, a Mini MC and him running around the circus laughing as he and his wife go about their routine. It was a picture right out of a movie.
MC felt guilty as her husband sounded genuinely happy about the idea unaware of her true intentions. Ofc she wants to have a family with him, she dreamed about it as much as he did if not more. she just wished it went differently.
Either way she let's her husband hug her and twirl her around, promising to be the perfect dad to their unborn child while she hides her face in the crook of his neck, her tears staining the collar of his costume, murmuring a silent apology that his ears don't pick up.
