James was fifteen all over again, staring at a haughty Lily Evans using her important voice. It was uncanny. Every bit of impatience he'd ever had for Lily Evans came rushing back to manifest itself for Lily Potter, his granddaughter, and it took all of James's willpower not to roll his eyes. Hadn't they already covered this.
"James Charlus Potter. As far as business, I suppose this is a rescue mission. But if you mean occupation, I was an Auror before I settled down to become a full-time member of the Order of the Phoenix. My patronus is a stag," here he paused to prove it, and a silvery stag erupt from his wand, and saw fit to stand beside him, before James continued, louder.
"my most prized possession is an Invisibility Cloak, which I gave to Albus Dumbledore a few weeks ago for safekeeping, and because he asked to borrow it. In my fifth year I became an Unregistered Animagus. My form is a stag, and if coming back from the dead hasn't infringed upon that ability, I can prove it."
He was tired of explaining, tired of telling this girl textbook reasons why he was or was not her grandfather, the father of Harry Potter, James Potter, husband of Lily Evans Potter. Closing his eyes, James transformed, and was a stag.
He blinked stupidly at her, pawing at the ground, and was back.
