Phil smiled warmly, something he really only did around the people he cared for, at he knew that whatever missteps he might've made, Darcy still thought well of him. When she asked if he'd consider doing it again, fathering a child, he didn't hesitate. "Yes. Whenever you're ready to." Because he'd wanted to go through this process with her in the first place and hadn't had any indication she'd changed her mind about it.
Now though, he had hope, and he stepped forward to put his arms around her waist, carefully holding her as she held his daughter. "I'm not in any rush but- as soon as this little one is with Arva until the end of my time here, I'll always be willing to have a baby with you." Maybe it was too much, too honest and raw, but Phil didn't want there to be any mistaking things between them.
