James Sirius Potter
1. He's never suspected that it was his mother's idea to name him James Sirius. He's always assumed that it was his dad, and as such has always tried to live up to the name as best he could.
2. No one thought to tell James that the reason Teddy Lupin had a different last name was because he wasn't actually James' older brother until the day of his eighth birthday. At first James was utterly shocked. Then he was angry. By the next morning he'd come to the decision that it didn't matter; Teddy was his older brother and who cared about silly old names, anyway?
3. James never realized that the Sorting Hat actually talked to the people it was sorting until he was told by someone else. It never said a word to him. In fact, the hat had barely touched the top of his head before calling out GRYFFINDOR! He sometimes wonders what the Hat would have said, had his sorting been longer.
4. The sorting of Scorpius Malfoy into Gryffindor came as a shock to the sensibilities of young James Sirius Potter, and though it would take years, this one event would cause James to alter his view about a great many things later on in life.
5. Late in his second year at Hogwarts, his cousin Fred would sneak James into a party being held by a bunch of fifth, sixth, and seventh years. At some point during the party, a mildly intoxicated Dahlia Parkinson cornered him. He would later forget precisely how he ended up at the party, but he never forgot the kiss she gave him that night.
6. For the rest of his life, he would continually poke fun of Albus after Albus became a Prefect and then later Head Boy, but secretly James couldn't have been prouder of his little brother. And the envy was something he swore he'd never admit, even under torture.
7. Albus might have got the cloak, but James got the map. He figured this was a fair trade until the day Lily got the racing broom. After that, the map just didn't seem as cool.
8. Oliver Wood, the legendary coach of British National team, told the Daily Prophet that the Chaser team of James Potter, Fred Weasley, and Roxanne Weasley was, perhaps, the greatest player combination he'd ever seen in his life. It was the proudest moment of James' life.
9. The worst day of his life was the day of the broom accident. It ruined his chances at a professional Quidditch career. Years later, when his sister told him she'd been signed with the Harpies, he hated her for it. Just a little bit.
10. To the day he died, James never forgave Harry for the fact that it was James who found his father's body.
