I don't own anything except details and maidoforange on LJ is who I saw first come up with Harry having additional portraits made for his home.
Harry felt a bit guilty because while he had come to visit the Headmaster, it was her office that he was more interested in. With a hand over the toddler's face, he threw down the powder and announced, "Minerva McGonagall's office."
The experience made the boy laugh and he was struck, not for the first time, at how different his sons were. James always cried and threw a tantrum at having to floo; preferring side-along apparition but being Hogwarts, this wasn't an option. His former Head of House wasn't present even though he had owled her although he'd rather do this part alone.
"Albus…Severus," he called and Dumbledore quickly appeared while Snape revealed that he wasn't really sleeping by opening one black eye.
"I have someone I'd like to introduce you to," Harry said as he struggled to hold onto the squirming boy who wanted desperately to get down.
"Is that James?" asked Albus, pushing up his spectacles.
"No, James is almost three and a half. This is the new baby," he explained before silently adding, although not for long, "This is Albus Severus Potter."
The old man beamed and exclaimed, "What an honor! Thank you, Harry."
Both eyes have shot open in the other portrait and Snape looked at the toddler. Originally, Harry and Ginny had planned to give their first born this name, but upon seeing him for the first time, they decided to wait and he'd become James Sirius Potter.
"He has Lily's eyes," he spoke and that was what they'd waited for, so Snape's namesake would have those green eyes that he wished to see as he died. Trying not to grin, he watched as his former Potions' professor excused himself through portraits to reach Dumbledore's for a better look and Phineas crowded into the frame as well. Young Albus watched with keen interest.
"Taza!" he yelled and stretched his left hand towards the moving figures.
"No, you can't touch," said his father and lightly grabbed his hand.
"He'd make a fine Slytherin," Phineas commented.
"If that is what he chooses to be," Harry said and readjusted his hold on the boy, "He's named after two great Headmasters and either of their houses would make me proud."
All eyes turned to Snape who looked away although what he could make out of the face was paler than usual. He heard the staircase move and the door opened for Minerva. It was strange to think of her on a first name basis and stranger still to notice how much older she appeared since he'd seen her last. She was eating something.
"Sherbet lemon?" she offered and set two on the desk, "They had them downstairs at the feast and I found I couldn't resist them…this time."
He couldn't honestly tell what she was thinking that caused the pained expression on her face and she answered the question without his asking, "This is my last feast, Harry. I won't be back next year."
How odd to try and picture Hogwarts without at least Minerva. There was a realization that he'd taken for granted that the ones who'd survived that final battle would always be there and he was struck by an impulse to tell her that Ginny was pregnant again even though they hadn't told a soul yet.
"I never liked Halloween," the woman admitted and he could understand. October 31st was inexplicably linked with the murder of his parents who should have been doting over their grandchildren just as much as Teddy should have been being taken house to house by his parents and not his grandmother. Exactly twenty six years had passed since Harry was made an orphan and it made him sad to think how he had not only outlived them, he was getting to do all the things they never would. It was a strange responsibility to live life the best he could because they couldn't. Young Albus leaned until his father set him on the desk and the toddler took one of the candies.
"Like his namesake," Minerva commented with a small smile before glancing at the portrait and he could tell it grew a little when she saw that Snape had left the confines of his own. In that moment, Harry decided something that he and Ginny had been in conflict over. His wife was so sure that the new baby would be a girl and wanted to name her Molly after her mother, but he wanted to name her Lily after his mother. At the time, there only seemed to be one logical way to settle it. Now he saw how incredibly childish it was to have a Quidditch match over it although she kept teasing him how she'd played professionally so he did get a certain satisfaction from reminding her, "Youngest seeker in a century." She responded by sticking her tongue out at him which James had mimicked and telling him that he had to come up with a middle name as well.
Lily Minerva Potter, he thought to himself.
"I'm not sure who is to replace me, but I don't know how kindly they would take to your visits to their office to talk to portraits," she warned him while taking the boy in her arms. Harry nodded and decided he should have some portraits made for his house.
