"Who's Mundungus?" Harry asked as he and Camellia dragged Dudley down Magnolia Crescent.
"One of the members of the Order," Camellia replied. When Harry looked confused, she said "Can't tell you anymore than that. Mad-Eye can, probably." Harry gave her a quizzical look, open his mouth , about to say something, then he thought better than to do so. "Well then, at least tell me who you are, and take that hood off," Harry demanded.
"Fine," Camellia said, and, rather reluctantly, pulled back her hood to reveal long, auburn hair and piercing blue eyes, and features otherwise looking like Lilly's. "I'm Camellia Potter, your older sister."
"Wait what? How?" Harry yelled in shock.
"Hagrid can explain it better. Ah well. When Voldemort came, our parents and I were reading in the living room. I was about six at the time. When Dad saw Voldemort, he told Mum and I to run. I had, for some reason, grabbed Mum's wand from the bookcase and when we got into your room, and Voldemort came in, I was firing anything I could at him using Mum's wand. She pleaded for our safety, but he killed her. As he started performing the Killing Curse on you, I fired one more time at him, which got him distracted, and once he finished the curse, it wasn't as powerful as it would've been without me there. He vanished in a haze of smoke. Hagrid came, picked you and I up, gave you to the Dursleys and me to Sirius, who for a while looked after me, before giving me to Dumbledore. I went to school, and left in the end of your second year. Now I'm as close to an Auror as you can get, without being trained."
"What?"
"Like I said, Hagrid explains it better."
Then they were at Number 4 Privet Drive. Aunt Petunia had been waiting by the door, and when she opened it, gave a small squeal of surprise. "Camellia?"
"Petunia."
