Albus Dumbledore was not known for falling into traps, and he certainly didn't wish to start now.

So of course, he used all resources available to him, including a few that some would say were a tad inappropriate for the headmaster to be using. There fore, before he would greet this stranger, he needed one thing.

The Marauders Map.

He slipped into Filch's office, easily of course, and retrieved the old parchment from a filing cabinet labeled 'Dangerous'. Of course there were only three people alive who knew how to use the Marauder's Map, and he, of course was one of them.

He stepped out of the castle, parchment in hand. "I solemnly swear I am up to no good." One lie couldn't hurt him.

He read the greetings from the Marauders and gave a sad, mournful smile. The words cleared and a map took their place.

Even as he neared the gate, Albus had yet to check the map. When he looked around and saw the man unconscious in the distance, he approached calmly, still not consulting the map.

He looked at the battered man below him and drew in a shaky breath. A silvery cloak lay beside him. His calm abandoned him; he finally inspected the Marauders Map.

A smile broke out Albus Dumbledore's face. The first genuine smile in a long time. The Marauders Map never lied.
