To be honest, Dominique likely would have started yelling at him for almost any sort of response. She was scared and her only way to alleviate that fear was to take it out on him. Dominique tried very hard to blink away her tears as she glared back at him.
"Happy? You think all that makes me happy?" She stormed past him, making to pack a bag to stay at Elena's. She wasn't going to be yelled at! "I wish you'd just be flipping honest with me straight out, Sirius. I'd be happy if you told me that without bloody yelling! I'm terrified that I'm going to be an awful mother, ruin this child's entire life, disappear mid-pregnancy and leave nothing but a half-grown baby in my wake. I don't need your anger right now. Really, I don't."
