A/N: My friend Lyra (the same one who told me to write That Weasley Girl) also gave me the idea to write about Snape's portrait. So I did, and here it is.
As soon as Severus saw the boy, he knew who he was: Potter's son. It was obvious. He didn't have the glasses or the scar, but his hair stuck up infuriatingly in the back and he had the same skinny structure.
And his eyes…
Severus winced involuntarily. He'd seen the other son in the Headmistress's office often, but the other son didn't have Lily Evans's eyes. Even as a portrait, he couldn't bear to see Lily's eyes on James Potter's face. It was close to excruciating. James hadn't deserved her, not even close. He'd been the picture of arrogance, while Lily had been…perfect. As close to perfect as a human being could be.
Severus forced himself to look up. The boy was fidgeting in his chair, obviously nervous. Why was he in the Headmistress's office in the first place? Maybe he'd been caught sneaking around with that accursed Invisibility Cloak. Severus felt a twinge of hope. It was a spiteful, malicious feeling, but he couldn't help it. He hated this boy on instinct, another wretched Potter boy, just like James…but with Lily's eyes...
To think Albus had expected him to forgive Harry Potter for having that piece of Lily. It had made things worse. He'd been living proof that Lily Evans had loved James Potter and not him.
A small part of him reasoned that it wasn't either of the boys' faults. He had to forgive someday. Well, maybe he did. But so far, he'd been given no reason to. Harry Potter had been just as smug and dim-witted as his father. The only good thing he'd ever done for Severus was to ensure him a portrait in the Headmistress's room and that wasn't enough.
Potter's son suddenly looked up. Severus craned his neck to see Minerva appear from her personal quarters. "Professor!" the boy blurted out, standing up so fast he stumbled, "Professor, I swear I didn't do it!"
"Albus," Minerva tried to interrupt.
So the boy's name was Albus, Severus noted. Well, he couldn't say he was surprised. Harry Potter and Albus Dumbledore had been close, for reasons he'd never understood. He was tempted to check Dumbledore's portrait to see his reaction, but decided against it.
"It wasn't me, you can even ask Hagrid -"
"Albus," Minerva said more firmly.
"I was with him the whole time, he'd invited me over to -"
"Albus Severus Potter!"
The name didn't register at first.
Albus Severus Potter.
Albus Severus Potter?
Severus stared down at the boy in the office, a constricting feeling growing in his throat. James's looks, Lily's eyes…and his name.
All at once, Severus Snape forgave.
