When Persephone had told him she wanted him to come to her home, he'd been slightly unsettled. Not enough to dissuade him from going, but it made him curious; why did she want him to come there? He didn't mind, of course, but it wasn't something she made a habit of doing, and he didn't like to intrude. Despite his hesitance, he would never say no to his daughter when there was something she wanted unless it put someone at risk. Since that wasn't the case here, he pushed away the negative thoughts. If something were wrong, she'd tell him, outright. There was no need to worry. Whatever she wanted to see him for, he was sure it was something good.
He knocked on the door, and it wasn't long before he heard sounds from inside of her moving about. A few moments passed before the door opened, and he offered a smile, moving forward to give his daughter a nuzzle before she began leading him through the hut. The small talk made him even more nervous as he conversed with her; it only seemed to be putting something off, and when she stopped at a door, he became even more confused. He didn't let himself react yet. There was no way of knowing what was going on until she actually told him, so he shouldn't jump to conclusions. As she opened the door and allowed him to look inside, however, his reservations disappeared.
His eyes immediately were drawn to the bed, where the cluster of children were safe from harm, protected by the home and their mothers. The expression on his face softened at once as he gazed at them, exhaling quietly as the corners of his mouth turned up. He allowed himself to remain for a few moments before he looked over at Persephone, brushing his muzzle against the top of her head.
"Congratulations, Percy," he said, toning back the excitement in his voice to a warm happiness. "I'm happy for you two. Do they have names?" He wouldn't want to refer to them without them if they did, but he'd understand if they hadn't yet. Their family had a history of misfortune when it came to children. He wouldn't blame her if she was scared to do so.
