Harry took a deep breath and stepped out carefully onto the wooden floorboards of the Astronomy tower, pulling the invisibility cloak smoothly from over his head as he went. He looked around carefully, his eyes catching on each small platform that jutted out into the free air, expecting to find Draco waiting on each one he looked at, his back to the night air, his eyes on Harry. But there was no one there. He licked his lips anxiously, and considered the map in his hand - the small dot that represented Draco hadn’t moved and was only a few millimetres from his own. The map never lied.
