It was later that evening when things began to click in Harry's head. Why did Katherine use a Patronus attack. And what meaning did the hawk hold? Afterall, his own Partonus spell produced the figure of a stag, which represented his father. What did Katherine's Patronus represent? Harry frowned and looked back at his text, feeling too ditracted to read about the assigned subject. He glanced up to Hermione, who was pulling on her cloak and preparing to go out for another patrol shift.

"Maybe could we come again?" Ron asked.

Hermioned huffed, "You remember the results of last time. I'm not going to risk it."

"But.. Hermione!" Ron whined.

"No Buts, I simply am not going to put you in a position like that. You could be expelled!" Hermione continued.

Ron frowned, "Prude."

Hermione glowered, "Perhaps, but look who's helping to protect your education. You really ought to be more appreciative of my efforts."

Ron would've continued if Harry had not cut in. "'Mione.. Be careful alright?"

Hermione smiled, "Of course, g'night, don't wait up for me." She then slipped out of the door, speaking a soft greeting to the Fat Lady, who had asked "where she was off to at such an hour" before dissappearing into the dark halls.

Harry, at the moment the door began to close, started to rummage through his pockets, pulling out some folded parchment.

"Don't tell me you'll be doing homework all night while Hermione's out having the fun.." Ron chided.

Harry gave a grin, "Of course not." He unfolded the parchment, mumbling a bit of an enchantment, "I solemly swear that I am up to no good," and he tapped the paper with his wand. The words began to appear on the parchment, showing an intricate map with moving names of all members of Hogwarts.

Ron scooted over, pointing to the name 'Hermione Granger' traveling down the hall. He pointed her out to Harry, but the boy was focused wide-eyed on another part of the map. His gaze was staring at the name 'Remus Lupin' that was stationary in front of the name 'Albus Dumbledore' in a classroom.

"Professor Lupin is here!" Harry exclaimed.

"Naw, didn't he leave.. cause of the.. ya know.. grr issue?" Ron said mimicking claws with extended fingers and letting out a mock growl.

"Yes, but he must be back! The map doesn't lie. Maybe he'll start teaching again." Harry continued excitedly, getting up and starting for the dormitory stairs.

"Where are you going, Harry?" Ron asked.

"We have to go see him." Harry said before running up the stairs, "I'm going to get my cloak, get ready if you want to come."

Ron got up and started folding the map, getting a bit excited and nervous as well. It was a known fact that Professor Lupin was a werewolf, one that almost killed them back in their 3rd year. But.. he didn't mean it, it was just the traditional werewolf rage.

Harry trotted down the stairs, his invisibility cloak over the crook of his arm. He took the map from Ron and studied it once more before refolding it. He tapped the parchment with his wand, muttering, "Mischief managed." And the text bled out from the paper.

The two slipped under the cloak and snuck out of the door to the Gryffindor dormitories, sneaking past a dozing Fat Lady who woke up when they passed. "Who goes there?!" she called. But the boys didn't respond and kept moving down the darkened hallways.
