Mother
I think this one was meant for the AU Lessons is set in, considering recent developments. I've actually got a prompt for something on this line I'm working on, but this was a fun what-if.
"Olivier, your mum knows I am pregnant."
"How did you meet my mother?" he asks, even as his stomach twists.
"She stopped by while you were out – apparently she wanted to meet the woman making a fool of her eldest." The mocking tone in her voice doesn't quite hide the anger as she continues, "She had already decided I was just marrying you for your money, but apparently now I've coerced you into it by carrying your bastard – or tricking you into believing that."
He's furious at his mother, is definitely calling her later to lay into her for this, but in the moment he's more concerned with the woman in front of him, "And?"
Her smile turns viciously satisfied, "I threw her out."
