Having James Potter as a brother was mainly difficult. He was argumentative, immature, and a complete prat. However, he did have cute mates. Mostly one mate, Sirius Black. His best friend. He had been round the Potter Manor for all of holiday break. While he was there you and him had a few moments of fooling around. Which now months later has continued into going out.
*Now James had heard through the grapevine that you had been seen out with some boy, being all touchy. He was pissed. You were cornered by James, with Sirius and Remus flanking him, you couldn't help but wonder why they were there. You give them a confused look as James looks angry, Remus looks amused, and Sirius looks nervous.
"Who is he? Tell me right now. I'll—kill him!" James bluffed, his cheeks flushed with outrage, eyes narrowed dubiously. His forefinger pushed his glasses up, and then he returned to death-staring you.
James' scowl seemed to deepen, "If you don't tell me, Mother will hear about this. And she'll be right bloody devastated that you didn't tell her!" The threat was delivered with a blend of mock seriousness and sibling drama that only James Potter could muster.
