"Hey, uh, Marinette? I think I lost the baby."
Marinette blinked, frowning. "You…lost her?"
"Ye-ah." Adrien shifted from foot to foot anxiously as Marinette hung her coat on a hook, and set her bag on the hall table. "I mean, she was right there, all day long. She kept following me around. And then she disappeared, and I can't find her anywhere."
"Did you leave a window open?" Marinette asked, toeing off her shoes.
He frowned. "I didn't open any windows at all."
"Did you leave the front door open at some point?" She crossed to the sofa and sank into the plush cushions with a sigh.
"No, I haven't opened that, either."
"Then she's around here somewhere." Marinette shrugged, unconcerned, and tipped her head back into the cushion behind her. "She'll come out when she's ready."
His frown deepened. "But Mari, she's just a baby!"
She laughed, and tugged him down to sit beside her. "Yes, love, I know. But she's a baby cat, and as such, is perfectly capable of managing on her own for a while. She probably just found a cozy place to sleep for a while."
"But—"
"Besides," Marinette continued, silencing him with a brief kiss on his lips. "She has Plagg looking out for her. He might be a grump, but he's not going to let anything happen to her."
"I suppose you're right." Adrien slumped into the couch, pouting. "It's just that I've never really had a pet before. I don't want to mess up."
"I know, minou." She kissed him again, this time letting her lips linger on his, drifting back and forth languorously.
"Mmm. Hello, my lady," he murmured against her mouth, hooking a hand behind her far knee and pulling her over to straddle his lap.
She smiled against his lips. "Hello, mon minou," she murmured back.
She'd just swept her tongue into his mouth when she felt the prick of tiny claws in her leg, catching in the fabric of her leggings. She broke the kiss on a giggle, scooped up the little ball of fluff before she could do any real damage, and presented her to Adrien. "See? She's just fine."
"Luna!" Adrien's eyes lit, and he cuddled the little cat to his chest. "You naughty girl, where have you been? You worried your papa sick!"
Marinette giggled again. "Oh Adrien, you're ridiculous. If you worry like that over our kitten, how are you going to survive worrying over our baby?"
"Oh, I don't know," he said, nuzzling the cat. "I'm sure I'll figure—" He stopped abruptly, and snapped his head up to meet her eyes. "Wait, what?"
She smiled joyously, and nodded to encourage his obvious train of thought.
"So, you're—you mean, we're—a-a baby?"
"I went to the doctor this afternoon to confirm it. You're going to be a real Papa."
