Luna
“Miss Lovegood.” Severus drawled.
Luna had been staying at the castle whilst her home was repaired and redecorated by her father and found herself with a moment, looking up at her former professors portrait.
“Sir,” she began airly, “I suspected you.”
“Did you now? And what exactly gave me away?” Severus asked, his eyebrow raised.
“You were always sad.” She shrugged, “you always had a quick stride but your walk changed, you should have been enjoying yourself and your position but you did not.”
“And that gave me away, did it?” He asked, amusement in his tone.
“Yes, sir.” She smiled sadly at him. “That and I saw you cry, I was hiding from you in a suit of armour by the astronomy tower. I go up there to think, sometimes as there’s surprisingly few Whackspurts up there.”
He looked down at the young woman, dumbfounded.
“I’d have comforted you but I think you’d possibly not have appreciated it so I snuck away. I’m sorry for leaving you.”
“That’s… it’s…” he was stunned by her ability to hone in so accurately on the minuscule changes in his behaviour but to have seen him cry? Maybe he’d gotten reckless towards the end.
“Either way, Professor, I think you did a splendid job of being a spy. I thank you for your time and for all the detentions with Hagrid. They were most enjoyable moments.” She smiled softly at the portrait of the man she’d never feared and skipped away to find her father.
Minerva strode over to the picture, she drew her eyes up to speak, to offer some assurance, but, he was gone.
