“This is a good thing, my flower.”
Ra’s was composed and calm as he watched you pace the floor of his bedroom, likely wearing a hole into the beautifully opulent carpet.
“I know it may not be what you want, but I am not leaving you. We can handle this.” His voice remains calm and soft as he speaks to you, all of it a cover for his true intentions.
The last time Ra’s loved a woman as deeply as you, she died before he could spend much time with her. Talia’s mother, Melisande, had been the jewel of his eye, and her death greatly rocked his world. He never thought he’d find another to love, until he met you.
So, of course, he was disappointed when he learned you didn’t want children. Talia was his only child, but Ra’s wanted more. If not to take his place as the Demon’s Head, then to simply have. His only grandson had left to live with his Father, and Ra’s had— though he would never admit it —‘empty nest syndrome.’
It’s only reasonable that he lies to you.
Ra’s tells you that he’s infertile because of the Lazarus pit— that, sometimes, the pit had adverse effects on people —and one such effect could be infertility. You believe him without a single doubt; he’d been alive for centuries and used the pit countless times. He knew more about it than you, so who were you to question his knowledge?
Ra’s convinces you to stop using birth control, which easily set his motion in plan. All that he needed to do afterwards was wait— and he didn’t have to wait very long before you were thrusting a positive pregnancy test into his face.
It’s easy enough to pretend he’s surprised, and you’re none the wiser to his plan. Ra’s wanted you tied to him in a way that was impossible to sever; and what better way to do that than impregnate you?
