Remus stormed into the dorm room, slamming his school books into his trunk. Sirius sat on his bed, reading a comic book, James was staring into space, most likely fantasizing about Lily, and Peter was polishing his wand. The trio looked up to find the source of the noise.

"What's wrong, Moony?" James asked concernedly, snapping out of his reverie

"Sirius." Remus growled, slamming the lid of his trunk closed.

"Still mad?" Peter asked sympathetically.

"Well, I was about to forgive him--" Remus began angrily, but was cut off by Sirius.

"Look, Moo—Remus. I told you, I really do regret what I did, I don't know what I was thinking – I – I wasn't thinking. I am sorry, truly, and I hope you will forgive me."

"Oh, you're sorry, are you?" Remus snarled. "Then explain this!" He threw the letter at Sirius, and picked his trunk off the ground.

"Hey, why are you packing?" James asked, sitting up and turning to face him.

"Ask Sirius." Remus said bitterly, and left the dorm, leaving a stunned silence in his wake.

Sirius dropped the letter in shock. "I've never spoken to that woman in my life," he whispered.

James picked up the letter, and looked appalled. "Sirius – how could you do such a thing? Hogwarts means everything to Remus! You know that."

"James! Peter!" Sirius said frantically. "I swear, I never spoke to that woman! In fact," – he squinted at the letter – "That doesn't even look like a woman's handwriting!"

"You're right," said James grudgingly. "It doesn't."

"Wait a minute… it looks kind of familiar, actually. I think I know whose it is."

James and Peter looked at Sirius questioningly, their feud momentarily forgotten.

"Who wrote it?" James urged him.

A look of dawning comprehension spread across Sirius' face.

"Well?"

"Regulus." He said simply.
