Nevada
It was well past midnight when the call came. They hadn't expected it to happen. They were too tired from stopping a house from killing anyone that entered it. It was hard, way too hard, but they had done it.
The incessant ringing of Dean's phone caused Sam to stir in his bed. He opened one eye, staring at the black nuisance. With a grunt he lifted himself on one elbow and used his other hand to grab the phone.
The number was a random caller, but not many people called Dean without having a reason. Sam flipped the phone open and pushed it to his ear.
"Hello?" He asked sleepily.
"It's nice to hear you Sammy," John Winchester's voice was unmistakable.
"Dad," Sam was shocked. "Where are you? Are you okay?"
"I'm fine, Sammy," his dad sighed. "Put your brother on the phone."
Sam was a little upset that his dad still couldn't talk to him after all that happened, but he woke his brother up anyway.
"Dean, wake up, its dad," Sam threw his second pillow at Dean, who groaned, but then jumped when he heard the word 'dad.'
"Hello," Dean said after he grabbed the phone from Sam.
In all of Sam's life, he never saw Dean's face change from being worried to be angry whenever he talked to his dad. And he definitely never heard him yell at their dad either.
"You what!" Dean growled into the phone. Sam didn't know what happened, but Dean shut the phone, slammed it down on the night stand, and threw the comforter over his head to fall back to sleep.
"So, no good news then?" Sam asked. He received a grunt before he too decided to fall back asleep.

Next Morning- Interstate
"So let me get this straight," Sam looked toward his brother as they drove through the desert. "Dad calls, telling you we have a younger sister and we need to save her from a Hellmouth?"
"Half-sister," Dean clarified.
"How can you be so calm about all of this after this morning when you freaked out?" Sam said getting angry. "He can't just drop a bomb on us like this and expect us to be okay with it."
"I'm not okay exactly," Dean sighed. "But I'm dealing. We couldn't expect him to not move on from mom."
"But a daughter?" Sam asked. "A daughter he apparently left to die on a Hellmouth."
"It happened in Los Angeles," Dean said. "The family moved to the place, Sunnydale and since they don't know what's really going on, they had no reason to move away from the place."
"What are we supposed to do when we get there?" Sam asked. "I can't see us knocking on the door and telling them what Dad said."
"We meet our half-sister and her mother and tell them a lie," Dean smirked. "We found out we had a sister and wanted to meet her."
"And then what?" Sam urged. They were going to have to work on the story, but at least it was something. "Dad wants us to protect the girl, Dean. Are we supposed to force her and her mom to move from the town before something gets them?"
"I don't know, Sam," Dean sighed. "Maybe we can take care of the problem ourselves and they won't have to leave."
"It's a Hellmouth, Dean," Sam said. "Unless you have latent magic abilities, it's staying open."
The rest of the ride was silent as both brothers tried to come to terms with their dad's biggest secret so far. They had a half-sister. And her name was…

"Buffy, look out!" Riley yelled as a vampire tried to attack his girlfriend. His warning fell on deaf ears as he was too far away for Buffy to hear. It didn't seem to matter as Buffy turned sharply and staked the vampire in the chest. As the vampire turned to dust, she changed her position again and staked the oncoming vampire who thought he could take her.
Riley staked the last of his vampires before calling the base over his radio insuring them the area was secure. He rushed over to Buffy, who jumped in his arms as he spun her around.
"At least now we don't have to hide this from each other," Buffy said as she kissed Riley on the lips.
"Or your friends," Riley laughed as he set Buffy down on the ground just in time for Willow, Xander, and Anya to emerge from a wooded area.
"Out playing paintball again?" Xander laughed.
"You can never just drop that, can you?" Riley smiled as they made their way back to UC Sunnydale. They bid farewell to Xander and Anya, seeing as Xander lived in the basement and Anya was in it for the sex.
As they made their way back to the campus, a car came barreling at them. Buffy barely had time to jump out of the way as it sped past her. After having a rough night of slaying, it was too much for Buffy as she quickly located a rock and threw it at the car.
"That was very unlike Buffy thing to do," Willow commented as the rock actually cracked the back window. "We should probably make with the running before they come back.
"It's been a hard week, Will," Buffy said. "We already lost our voices. And now, demon activity is high and Professor Walsh is being a major bitca by giving us a test."
"Her T.A. is standing right here," Riley chuckled as he raised his hand.
"And you're a good T.A., but Walsh is trying to kill me," Buffy groaned.
The rest of the walk was pretty much without incident. They passed the dorms in silence, expect for one which was having a party, but that was common for that particular dorm. Riley gave Buffy a kiss goodbye before leaving for his own dorm to report to Walsh for the night.
"So, study party tomorrow morning before the test?" Willow asked from the bathroom as she changed for bed.
"I'm gonna need it if I plan on passing the class," Buffy sighed as she put her weapons away. Before Buffy had a chance to prepare for sleep, the phone rang.
"Mom?" Buffy asked confused. "It's a little late."
"Buffy, I have something to tell you," her mom said. "I can't tell you over the phone, so I need you to come over tomorrow."
"Sure mom," Buffy said worried. "I'll be over after class. Is something wrong?"
"No, but what I have to tell you is important. I'll see you tomorrow. I love you, sweetie."
"Love you too," Buffy said as her mom ended the call.
"Something wrong with your mom?" Willow asked as she emerged from the bathroom wearing her pajamas.
"I don't think so, but she has something to tell me," Buffy answered as she looked to Willow.

Next Day- Summers' Household
As she walked down the street of Revello Drive, Buffy had tried to figure out what her mother had to tell her. She was thinking about it all day, actually. She was distracted during the study session, which led to her being distracted as she took her Psychology test.
Luckily, Willow sat right next to her and kept kicking Buffy to stay focused on the test. She had managed to get through the test, but her mind continued to wander about the subject of her mom's news.
Was she in trouble?
Buffy could think of nothing that could get herself in trouble with her mom. She's rarely home to begin with, so there wouldn't be a chance of her mom finding anything out.
As she approached her house, she saw the car from last night. And there was the crack in the glass where Buffy threw the rock. Willow was right; this was totally unlike Buffy.
"At least it wasn't a boulder," Buffy said to herself as she climbed the steps to her home. She unlocked the door, ready to face her mom with her big news and the person who drove the car who probably told her mom what she did.
Maybe that's why she wanted to talk to Buffy…
As she opened the door, she heard several voices coming from the living room. She walked slowly, expecting to find someone threatening her mother.
What she found were two men. They looked older than her, but she found herself in no way attracted to them.
"Buffy," Joyce stood from her chair. "I want you to meet Dean Winchester and his younger brother, Sam."
The brothers nodded after they stood and Buffy smiled. "Sorry about your car."
"That was you?" Dean yelled. Sam put his hand on Dean's arm, trying to calm him down.
"Don't worry about it," Sam sighed. "We can get it fixed."
"I'm not even going to ask," Joyce shook her head. She looked at her daughter and didn't stop the tears that started falling.
"Mom, what's wrong?"
"There's something I have to tell you about your father," Joyce sniffed.
"He's not my dad," Buffy rolled her eyes. "Trust me, I know."
"Y-you know?" Joyce asked. "How?"
"Besides the fact that I look nothing like Hank?" Buffy smirked. "Before we moved, and before the divorce, I heard you guys fighting. He said something about me not being his and I actually believed him. It made sense."
"Why didn't you tell me you knew?" Joyce asked with fresh tears in her eyes.
"You tried so hard to keep me from finding out and I didn't want all your hard work to be for nothing," Buffy shrugged. "But I always did wonder who my real dad was."
"I think this is where we come in," Sam spoke up from beside Buffy. "Your dad's name is John Winchester."
Buffy stood motionless, just looking at Sam who smiled weakly. For some reason, Buffy was adding two and two and was getting five. The number was subtracted by one a few seconds later, when she finally got four.
"Oh."
----------------------
I know, I should be updating other stories, but I had to do this one!
Also, I don't really see any stories where Buffy already knows she isn't Hank's daughter, so I tried for something different! What do you think?
Only a two-shot…
