Artemis and Kellin had decided to skip the middle man and go straight to Hogwarts to visit Kellin's father. They'd only met a few times since they'd begun dating, much to Art's disappointment, as she found him the loveliest peach and a great snuggler. She wanted to show Kellin around her old school, and as they walked up the corridors holding hands, they got a few amused looks and some ill-muffled "Aww's" that neither of them noticed. Art still remember her old school schedule, and she was counting on Arvo not wanting to walk down all those stairs three times a day for lunch, so she knocked on his office door with some confidence.
Artemis was quite right. The Arithmancy professor was in his office having some tea with a cupcake that had just finished its dance. He had sent a congratulatory letter to his son about the birth of his first child, though he planned on visiting the couple to have a good look at his new grandchild, but with the year being quite busy, he just hadn't had the time to do so. A knock on the door made him look up from some papers, and a hearty hello called for the visitors (whom he assumed to be students) to come on in. He was in a marvellous mood.
"Papa!" cried Artemis in greeting, holding up the baby Lion-King style. Her own father was Dada, but Arvo had soon acquired his own affectionate moniker. "Surprise!"
Arvo immediately acknowledge the little bundle that, to those of a more normal size, would have been tiny. But to the three of them, he was rather perfect. In a moment of rare dexterity, Arvo hopped out of the chair and rushed over to properly meet his new grandson. "Oh, look at those rosy cheeks! He's beautiful."
