I really love the idea of this, I don't even know why.

Also, shoutout to the inspiration of this OC- the lovely Kem'Ajiana

"No." Sirius said firmly. "Absolutely not!"

"She's not that bad." Remus said, crossing his arms.

"She could be a Death Eater!" Sirius argued.

"You weren't too concerned about that when you met her." Remus said casually, leaning against the counter. Tonks was sitting at the table, drinking tea and simply just listening to the exchange.

"You can't just hoard strays-"

"Strays?" Remus asked, laughing. "She's not a stray!"

"No, no, she is!" Sirius accused. "This is you, this is all you do! You just gather strays-"

"I would argue that it's what you and James did, actually." Remus said quietly. "But at least this one doesn't have fleas, Pads."

"I don't have fleas!" Sirius said. At Remus' raised eyebrow, he sighed. "Anymore."

Remus smirked and Tonks laughed loudly.

"Besides, it was only that one- okay, two- times." Sirius said quickly. "Molly helped handle that issue as soon as we began using Grimmauld-"

"Anyway, whether or not you still have fleas-"

"I don't."

"-Erin is going to live with us." Remus said calmly. "Besides, it'd be good for Dora to have another girl around now that Molly and the Weasleys are back at the Burrow."

"I have never hated you, Moony. But right now-" Sirius began. "She's not a girl, she's a-"

"Please don't finish that sentence, Black." Erin's voice said from the doorway.

"Hi, Erin!" Tonks greeted cheerfully.

"Tonks, Remus, Black." Erin greeted.

Remus walked over to the table, sinking into a chair next to Tonks. She slid a cup of tea towards him. "Erin, would you like tea?" Remus asked.

Erin sunk into a chair as well. "I really don't like tea."

Sirius scoffed, and Erin shot a look at him. "I prefer coffee." She continued.

"My mother's old coffee pot might still be in one of the cupboards, if you can get it to work, we'll make sure to get coffee for you." Remus said.

"Thanks." Erin said, grinning.

"How can you not like tea?" Sirius demanded.

"It's easy to dislike things, Black." Erin commented.

"So, what did you do in America, Erin?" Remus asked before Sirius could respond.

"I was an Auror until last year." Erin said.

"How old are you?" Sirius asked. "40? 50?"

"32." Erin said, shooting a dirty look at Sirius. "What about you? 65?"

"Sirius just turned 37."

"And what about you, Remus? Older or younger than Black?"

"Younger, actually. I won't be 37 until March." Remus said. "Dora turned 24 a few months ago. So, do students qualify to start Auror training right out of school?"

"Usually. I didn't start training until I was 24, I was qualified by the time I was 27." Erin explained.

"Are you one of the pureblood heiresses?" Sirius asked.

"Are you?" Erin shot back. She turned back to Remus and Tonks. "Purebloods in America are very different from the purebloods here. For instance, I don't think I've heard of a single pureblood killing a muggle- we just don't marry them. But here-"

"There's a whole group doing just that." Remus said. "You picked a strange time to move here."

"Oh, it wasn't a coincidence." Erin said. "It was boring back at home."

"Where are you from?" Tonks asked.

"Dunsmuir, California." Erin responded. "Had to travel all the way to Boston for school-"

"You were a Slytherin, am I right?" Sirius asked.

"What the Hell is a Slytherin?" Erin asked.

"One of four Hogwarts Houses." Remus said. "I suppose you went to Ilvermony, though?"

Erin nodded proudly. "I was a Thunderbird."

Sirius scoffed. "Is that the American Slytherin because-"

A Stinging Jinx hit Sirius in the arm. "It's the house of adventurers, you complete nimblypuff!" She said, stowing her wand back beneath her robes.

Sirius rolled his eyes. "You're a complete-"

"Anyways, we're going to go." Remus said loudly. "Dora, I can show you the garden spells I mentioned earlier."

"Oh, of course." Tonks said, standing with Remus.

"We'll let them kill each other in peace." He said as they walked towards the back door. "I haven't seen this much tension since Lily and James in our sixth year." He said to Tonks as they disappeared out the door.

"Who are James and Lily?" Erin asked. "Potter? You knew them?"

Sirius rolled his eyes. "I don't like you, you know."

Erin sighed. "What a heartbreaking statement, Black."
