Sure! Imagine, in this scenario, that Moody was hired by Dumbledore to basically be the security guard at Hogwarts. I always loved that idea.
James couldn’t sleep.
The twelve-year-old tightly closed his eyes and willed himself to start dreaming, to no avail. He finally sat on the edge of his four-poster, his mind buzzing. He opened the drawer of his bedside cabinet - carefully, as to not make a sound. He spotted the purple vial, filled to the top with a bubbling potion. It always knocked him out but he hated taking it.
James stuffed his feet into his slippers and pulled on his dressing gown. He tiptoed out of the room, catching his breath as the door creaked. He finally made it down to the common room and then into the corridor. He wandered aimlessly through the castle, allowing his head to clear. As he turned the corner on the third floor, he spotted a familiar face.
The Auror jumped and growled, “Jeez, kid. I’m gonna have to start putting a bell around your neck.”
James chuckled and Moody added, “What’re you doing up?”
“I can’t sleep,” James admitted.
“It helps if you’re lying in a bed.”
“I couldn’t sleep,” James corrected, “So I decided to go for a walk.”
“Do you want me to read you a bedtime story?” Moody wryly asked, “Get you a class of warm milk?”
James tried to laugh but it came out as a grimace.
Something in Moody softened and he asked, “What’s wrong, kid?”
“Have you heard from my dad?” James whispered.
Moody hesitated and admitted, “Not yet.”
James swallowed and Moody added, “But you know that that means nothing. An Auror doesn’t always have communication available; especially if they’re close to the enemy.”
This didn’t make James feel better.
“Your father is one of the best Aurors that I know,” Moody quietly said, putting a hand on James’ shoulder, “He’ll be fine.”
“D’you really think so?” James hopefully asked.
James could tell that he was sincere.
“And if I hear anything,” Moody continued, “I promise that you’ll be the first to know.”
The Auror nodded and said, “Now, get back to your dormitory before a prefect sees you. And try to get some sleep. Otherwise you’re going to become as paranoid as I am!”
James laughed and said, “I don’t think that’s possible. Goodnight, Moody.”
