Harry-Jamie (Sirius-Ginny)
Having just spotted James and Sirius arrive, Harry smiled. He was only too eager to give Jamie is present and had wanted to for days. It wasn't perfect, perfect would have been the real thing, his cloak, passed down through the generations as it was supposed to be, but he couldn't risk it ending up in the hands of Voldemort, not when he was already asking for the Hallows.
James would get the real cloak eventually, but for now he'd get the next best thing. The best invisibility cloak that money could possibly buy, guaranteed to last for at least a decade. It was the best on the market, and the best protection Harry could think to give at the moment.
Getting the package from under tree he went over to Jamie. "Happy Christmas," he said with a smile.
