They got back to the common room without much further ado. No one else was there; they were all off at dinner. James and Lily were on totally different sides of the room and Sirius and Xenia were still on the couch, they were sitting up and talking now, though. "Well, should you tell them the news or shall I?" Erin asked.

Remus grinned. "Erin here just beat up Snivellus good."

"Really?" Sirius asked his interest perked.

"Really." Erin grinned.

"I've never seen the bloody idiot run so fast and crying like a little girl." Remus said looking like the memory was the best thing he had.

"Mostly cursing the 'wild bitch'." Erin laughed.

"Well if I had a hat it would certainly be off to you, darling." Sirius said.

"Thanks." Erin said. "But with parents like you how could I have turned out any differently?"

"Yeah, Sirius, how could she of?" Xenia winked and then she looked at Harry. "If she's our daughter…"

Erin blushed. "I didn't mean like that!"

Harry more than blushed, he went practically scarlet. "Hey, uh…she didn't…"

"Oh, relax." Sirius said grinning and flopping back on the couch like a dog. "Like we care."

"I can see that." Erin said. "And when I get home you are getting an earful, Dad."

"Siri's in trouble! Siri's in trouble!" Xenia teased lightly.

"Ah, hell," Sirius said unconcerned. "I'm always in trouble."

"You won't be so happy when she gets done with you." Harry said.

"Definitely not, even if I do have to send it in a Howler."

Sirius just laughed. James however was looking very perturbed about something. "I'm surprised at you, Sirius."

"Huh, why?" The tall young man didn't look at him; he wasn't even concerned that someone was talking to him.

"I have never seen you accept something like this so easily. I would think you would need some sort of proof." James stood there and eyed Harry and Erin suspiciously.

Sirius sat up and narrowed his eyes. James may have been his best friend, but sometimes that boy had a real stick up his ass. "I've had my proof, Potter." No one else could have known about him being an Animagus…but all he said was, "And Xenia's visions told her they were coming and all."

James rolled his eyes. "I think we need more proof than an amateur seers' word on it."

Sirius growled and Xenia looked about ready to cry. "Potter, unless you want a thrashing I would suggest you stop right there."

James ignored him. "I propose a test, we will each ask a question and then we will see if they are truly our children. If they are who they say they are, they will know the answers."

"That sounds fair." Lily said.

Remus didn't know about all this. He knew that they didn't know their parents well and he had some ideas of why that was. He didn't want to say anything, but it seemed to him something was going to happen, something terrible and Harry and Erin weren't going to be able to know them. He knew they were who they said they were. How else could they have known? "Remus?"

The boy looked up. "From our talk I know they are who they say they are."

"Sirius?" James asked.

"I know she's my daughter." He said not at all liking what James was doing. "She already proved it to me."

"Lily?"

The girl looked at them and bit her lip. "What's my sisters' name?"

"Petunia." Harry said without even thinking, but he did stifle a sigh of relief.

Lily nodded. "That's right."

James nodded. "Xenia?"

The other girl was stilling looking rather like she might cry. "What's my middle name?"

"Celestina." Erin answered. She only knew that because she had seen her adoption papers. They weren't signed, of course, but Remus had all her legal work and the papers had shown her parents full names and Remus', oh Hermione was going to be jealous! She had tried to figure out Remus' middle name all year.

"That's right." She whispered.

James thought a moment. "What does the term 'Marauder' represent?"

"It is the name of your group." Erin started. "You are the Marauder's and your names are Moony, Padfoot, Wormtail and Prongs. Now if you'd like me to go into why you have those names, I can."

"What about you?" James asked Harry.

"Marauder can also represent the map you made of Hogwarts and the grounds." Harry said amazed what Erin did know. He thought he shouldn't be though.

James scowled. "Fine." He shrugged and went back to his table.

"I think he believes you now." Sirius said looking smug.

"Ah, who wouldn't?" Erin sat down next to her dad. "Who could resist such a face?"

Xenia leaned over and patted Erin's cheek. "Your dear old Dad, I am sure, can't resist you. You must get everything your heart desires."

"Well, I wouldn't go that far." Erin laughed. "But I know you guys love me."

"Of course we do, pet." Sirius smiled and put an arm around his daughter. He was a little surprised that after only about two hours he could love someone the way he did Erin. He knew without a shadow of a doubt that she was his daughter. He had helped to create her. And it did give him hope that Xenia would stop saying no.

Erin suddenly burst out laughing. "I was right, Harry!"

"About what?" the boy asked from his chair.

"They haven't had sex yet."

James and Lily both turned to stare at Erin and Remus turned bright red. He certainly did not want to hear anything about anyone's love life. Sirius and Xenia were also looking at Erin, but they looked amused instead of startled. "And how do you know that, love?"

Erin grinned guiltily at her dad. "Ummm…"

"She's a Legilimenist." Remus supplied. "She can see memories and hear thoughts that are in your head."

"Oh." Sirius said. "I'm liking this better all the time. Anything else you can do, pet?"

"Yes." Erin said and whispered in his ear.

Sirius mouth dropped and then he jumped up. "Yes! Yes! James! There is no doubt! She's definitely my daughter!"

James raised an eyebrow. "And how do you know that?"

"Because she's an Animagus! Just like I…am…" Sirius suddenly stopped. "Uh…"

Xenia and Lily both looked at him quite surprised. Sirius sat down again and pretended to be innocent. "So, how are we going to arrange this tonight? Harry can sleep in our room, that's not a problem since we have the dorm room to ourselves…"

"You're a what?" Xenia yelled at him.

Sirius swallowed, but still tried to get himself out of the immense trouble he was now in. "Maybe Erin can be invisible and sleep in your dorm that way, Lily."

"Sirius Black! You've kept this from me!" He was whacked upside the head.

"OW!" He said. "Xenia, I'm sorry! We swore to keep it a secret! Please! I didn't mean to keep it from you! But I had my friends and our vow to consider!"

"Did you ever tell her about you and James kissing?" Erin suddenly asked. Hey, she was curious.

Sirius' head whipped around and his mouth was agape. "Oh, shi—" He jumped up and Xenia was right behind him.

"What else haven't you told me?" The small redhead yelled hitting him and chasing him around the common room.

Lily was staring at James looking quite shocked. James rolled his eyes. "It's not what you think!" He yelled over Xenia. "Which one of us told you about that?" He asked Erin.

Erin and Harry both just pointed to Sirius, who was under heavy attack at the moment. Remus sighed. "That is something I could have kept out of my mind. Well, you did mention it earlier, but I don't want to think about it."

"Well, I was just curious." Erin said. "Because he said it when our friend Ron said he was sure that James and Dad didn't kiss like Harry and I do…and Dad said he could tell us, but he didn't want to frighten us."

James rolled his eyes. "Sirius!" He thought it bizarre he was annoyed with his friend for something he hadn't even done yet, but still! It definitely wasn't what everyone was thinking.

Sirius was ducking behind a chair and Xenia was hot on his heels hitting him with a tidy spell from her wand. "Get back here, Sirius Black! We are going to have a nice long talk about you keeping things from me!"

"If I stop I know we won't be talking!" He called back. "You'll be beating the crap out of me!"
