Submission for:

War of Angels Competition: Round Three - Teddy Lupin. Secondary character - Minerva McGonagall. Relationship - mentorship

Teddy crossed his arms, leaning back in the desk as he waited for the elderly Headmistress to return to her office. This was a usual occurrence around Hogwarts hallowed halls these days, even though the young Lupin had just started school a few months ago.

"For adding soap to classmates' ink pots, I want you clean and refill each and every one of them," Professor McGonagall said as she placed a large bottle of ink on his desk. "The ink pots are next to the sink over there," she added, while pointing to the corner.

The corner of his mouth curled as he picked up the ink bottle and rose from his chair. He just wanted to have a bit of fun, and everyone laughed when he began to blow large black bubbles.

"Wipe that smirk off your face, Mr Lupin," Professor McGonagall chided him. "I had hoped you would have inherited your father's love of learning instead of his affinity for mischief-making."

Teddy's mouth opened. "You knew my dad?" he asked. Did everyone know him?

"Of course I did," she said as she sat behind her desk. "He and his friends used to turn this place on its head during their days here but they were all sharp as a tack. When he got older, he even took a position as a professor here."

"What about the War?" Teddy asked.

He could see the older woman's face pale slightly, reminding him just how old she really was, before she shook her head. "I don't think now is the time-"

"I want to know," Teddy said. "Please, Professor."

Professor McGonagall sighed before she said, "Your father was a brave man who always stood up for his friends and colleagues. Even in the First War, he never left the fight before everyone got away safely. It was a shame to see him fall that night."

Teddy's head fell as he contemplated his professor's words. Not many people liked to tell him of his father's involvement in the Battle, even Aunt Hermione liked to sugar-coat it for him. But he wasn't a little kid anymore. He wanted to know the entire story, including one that had haunted him for so long.

"Do you know anything about Greyback?" he asked.

Professor McGonagall paused again and Teddy thought maybe he had probably asked too much at one time. Then she said, "Greyback was a ruthless man who liked to turn small children into werewolves like himself. Unfortunately, your father was one of those children he had bitten."

Teddy swallowed. "And whatever happened to him?"

Professor McGonagall shook her head. "No one knows. After the Battle, he simply disappeared and his body was never found."

Teddy nodded. So he was possibly still around, still out there and simply biding his time.

"Don't," Professor McGonagall said.

He looked at her with wide eyes, wondering what she meant.

"I've seen that look on enough faces. Teddy, you are young and inexperienced. You are no match for a werewolf like Greyback," she said.

"I wasn't..." he began, shaking his head quickly.

"But you might," she said. "Please, promise me you won't ever go after that man."

He nodded. "I promise."
