-Next Morning: 9:30-

Theresa apperated to 12 Grimmauld Place. She knocked on the door which was opened by Sirius. He smiled.

"Hi, Theresa," he said," He'll be down in a moment."

5 minutes later, Harry came downstairs yawning. He saw Theresa and blushed crimson.

"Uh, hi," he said," Sorry about yesterday, but thanks."

"No problem," she laughed," Feeling better?"

"Much," Harry grinned," Um...wanna stay for breakfast?"

"Oh, a...I ate," she said.

"Well, stay anyways," he said," Company will be nice."

"You're telling me," Sirius muttered, going into the kitchen.

Harry and Theresa exchanged a glance, but followed him into the kitchen.

"So, Theresa, any progress on finding you father?," Harry asked.

Sirius suddenly took interest in the conversation.

"No, nothing. I only just found out my mum was killed by Voldemort," Theresa said.

"She who?," Sirius asked.

"Her mother, Daisy Carter," Harry said.

Sirius almost dropped his mug of coffee, which he was drinking from.

"Daisy Carter?!," he spluttered.

Harry and Theresa gave him strange looks.

"Uh-huh," she said.

Sirius stood up.

"I have to go," he said, walking out.

Theresa looked at Harry, who shrugged.

"Maybe I should go...," Theresa said, slowly getting up.

"NO, um...let me just...go talk to Sirius," Harry said, having her sit back down," Excuse me."

He got up and went to Sirius's room. He knocked on the door.

"Sirius? Can I come in?," he asked.

Sirius opened the door and went to sit on a chair in the corner. Harry shut the door behind himself.

"Sirius, what happened?," he asked.

"I told you before that I was working on something, right?," Sirius said.

"Yeah," Harry said, sitting on the bed.

"Well, what I was doing was looking for...my daughter," Sirius said.

"You had a wife?," Harry asked, surprised.

"Yes, your mum's best friend, Daisy Carter," he said.

"Wait..." Harry said, shocked," Daisy Carter...that is Theresa's mum. So that means..."

"I'm her father, Harry," Sirius said.

"She is your daughter?," Harry said," She is Theresa Black?"

"She looks very much like her mother," Sirius sighed," I should have known..."

"Daisy must have been very pretty," Harry muttered.

Sirius smiled.

"She was," he said," Harry, I can tell you fancy my daughter."

"No, I don't," he blushed," We're just...just friends."

Sirius grinned and rolled his eyes.

"Alright, Harry," he said.

"You should tell her, Sirius," Harry said.

"I will or she'll keep looking for me, won't she?," Sirius chuckled.

Harry smiled.

They walked back to the kitchen. Theresa was playing with her watch when they walked in.

"Theresa...I'm your father," Sirius said.

She looked shocked for a second. She looked at Harry, who nodded.

"Wha-WHAT?!," she said.

"Your mother, Daisy Carter, married me," Sirius said," She became Daisy Black and we had you. When I was sent to Azkaban, you were s-sent to an orphanage. Your mom was at James and Lily's when Voldemort went there and he killed her. You were there, too. You survived because of Harry, I suspect. Hagrid found you and you were sent to an orphanage. People said, before I was proven innocent, that I had no idea your mother and you were there or else I never would have sold James and Lily out to Voldemort."

Theresa's eyes filled with tears.

"D-dad?," she asked, unsure.

Sirius nodded.

Theresa ran to him and hugged him.

"I missed you so much," she said.

"I missed you, too," he said, stroking her hair," You look a lot like your mother."

Theresa smiled. She turned to Harry, who was smiling. She ran up and hugged him.

"Thank you," she said.

"For what?," he asked, bewildered.

"If you hadn't have wanted to be my friend, I might have never met my dad," she said," Also, if it weren't for you, I might not be alive."

"Oh, well...you're VERY welcome," Harry said, extremely glad he had kept her alive.

Theresa kissed his cheek, causing him to blush.

"I have to go tell Aunt Mary, I'll see you later," she said to them.

She apperated away.

Sirius walked up to Harry, smirking.

"Oh, yeah, that blush on your face just proves you like her ONLY as a friend," he said," You are VERRRRRRY welcome, Theresa. Can you PLEEEASE let me-"

"SHUT UP!," Harry said, walking away.

-At Aunt Mary's-

"I'm happy for you, T," she said, hugging Theresa," Now, what about that Harry Potter boy?"

"What do you mean?," Theresa asked.

"Well, you two seemed to like each other," Aunt Mary said.

"I liked him years ago in my 5th year, Auntie," she said," That was the year he went out with Cho Chang. I don't like him like that anymore."

"Sure you don't. I never liked that Chang girl. Ended up with Davies," Aunt Mary said.

"Look, I have to go," Theresa laughed," I'll talk to you later."

"Say hello to Harry for me," she said.

"Okay, bye," Theresa answered.

"Bye, dear."
