Harry pulled a suitcase out from underneath his bed, opened it, and magicked all of his clothes and toiletries to fold themselves neatly inside. After slamming his suitcase shut, he threw on a traveling cloak and, bag in hand, left the room. He paused on the threshold, gazing at the flat he'd lived in for over a year, until finally landing on that blood-splattered cloak. An ache in his heart, he folded the cloak neatly and put it inside his suitcase.
"Reducto," he whispered, causing his suitcase to shrink to the size of a matchbox. As he opened the door he placed the miniature suitcase into his pocket and, taking one last glance, walked outside and shut the door behind him.
Where he came face to face to a grimacing Ronald Weasley.
