Author's Note: Big Brother is my other main summer show, and I've been watching old episodes recently, and watching both Big Brother and The Fosters tonight made me want to put the two together. You don't have to be a fan of Big Brother to read this fic; I will try and explain everything the best that I can within the story itself. Each chapter is a day in the Big Brother house, and will focus on Brandon and/or Callie throughout the day.

Let me know what you think, and enjoy! :)

Callie walked down the walkway with the other houseguests; she clenched her bag tightly in her hand and adjusted the strap on her shoulder. She would have never pictured herself doing a reality television show, of all things, but for the fact that her friend had cajoled her into applying. And somehow, here she was, about to enter the Big Brother house for hopefully the rest of the summer.

She flicked her eyes over the other houseguests as they moved into formation. There was an alternative-looking redhead, two blonde girls that looked nearly interchangeable, a black guy, a guy with a neatly trimmed beard and mustache, and then - what was he doing here? She looked away, before her facial expression could expose anything. Brandon Foster. Her former foster brother, whom she hadn't seen in almost four years, was standing right behind her, a matching bag on his shoulder. She hoped he didn't notice her.

"Houseguests, welcome to Big Brother 22 - a summer-long power struggle is about to begin. When I call your name, you may enter the house and claim your bed," Julie Chen said to them over the screen. "Adam, Ginny, Lauren and Brandon, you may enter the Big Brother house."

Brandon walked through the door and pumped his fist, as Ginny let out a scream and Adam waved his hands in the air. It was kind of awesome being one of the first four people to enter the Big Brother house, and be among the first to take in the design choices the team had made that year. There was a giant outline map of the world on the wall.

"Guys, the Japanese bedroom is so cool!" Lauren said, running out from where she had thrown her bag down. "It looks like they're representing different countries."

Brandon went into the room Lauren had just left to check it out. The painted cherry blossoms on the wall were perhaps a tad too pink for his liking, but it was a cool room. Definitely very serene, and he liked the little automated babbling brook along one wall. "What the heck," he muttered under his breath as he threw his bag down on the bed next to Lauren's, and walked back out into the main living area. "I'm Brandon, by the way, if Julie didn't make it obvious out there," he said, shaking the other guy's - Adam, by process of elimination - hand.

"Dude, don't sweat the intros right now," Adam said, laughing and slapping Brandon's back, "we're going to get to talk all about ourselves with a little bubbly in a bit, once the others get in here and find their beds and shit."

"Okay, cool," he said, watching as the second group came in from outside. The energy in the house tonight was almost electric in its composition.

Callie was one of the last four left standing outside. Everyone else had gotten to go in - Julie had listed off the names: Cierra, Denzel, Jarrett, Evan, Terance, Rebekah, Andriana, Joy. It was just her, an eerily pale girl with extremely dark hair, a blond all-American looking guy, and the girl's slightly more pigmented counterpart. "Lynn, Zachary, Liam and Callie, you may now enter the Big Brother house."

She walked through the doors with a smile. She wasn't going to whoop and holler like Liam was doing, and the others had done. Oh, she was probably going to make for very boring television at this rate, and she hadn't even put her bag down yet. "I hope we can find beds," she said to the girl - Lynn, she believed her name was.

"Yeah, well, if we don't, I guess we just end up sleeping on dirt in the backyard," she said, shrugging her shoulders. "You never know with Big Brother."

Turned out, the only beds left were to share with another person, in the Caribbean beach resort-esque bedroom. "Mind if I share with you?" she asked a brunette girl sitting on one of the beds. "It...doesn't really look like I have other options right now."

"Sure, yeah, hey," she said, patting the bed next to her. "I'm Joy, by the way."

"Callie."

"Cool to meet you, Callie."

"We're opening up champagne in the living room if everyone wants to join us!" an impossibly tall woman said, yelling into the room.

Callie and Joy exchanged looks. "You wanna go?" Callie said. "Because we could just blow that joint and sit here and get to know each other." The thought of sitting just across a coffee table from Brandon was too much. She was doing this to get out of her shell, live a little more on the edge. Not to face old things that she thought were long since buried.

"We should probably go. They'd wonder about us. C'mon."

The impossibly tall woman's name was Andriana, the alternative redhead was Rebekah - "Becks," she said, with a drawn out accent, "but if you insist, I'm Rebekah" - and the others went around introducing themselves. And then it came around to Brandon. "I'm Brandon, 21, from San Diego, and I'm a musician," he said, toasting his glass of champagne in the air.

"What kind of music do you play?" one of the blondes - Ginny, they'd learned - asked, leaning over toward him and smiling up at him.

"Mostly piano, but I know some guitar too."

Everyone nodded and smiled, and the introductions continued on - Denzel, the accountant and Lynn, the economist from Ohio and Cierra from Kentucky - until it got around to Callie. "Uh, hi, I'm Callie, I'm 21, I'm from Ventura, California, and I'm a freelance photographer."

"Very cool," Brandon said, and Callie had to bite her lip to hide the smile that threatened to form on her face. This was going to get interesting, fast.

Brandon (diary room): I'd know that girl anywhere. I haven't seen her in so long, but seeing her makes me feel like I'm 16 again. In a good way. Callie. I've missed her.

Callie (diary room): I'm still not sure how I feel about Brandon being here. He hasn't changed a bit, that's for sure. Are we the only ones that know each other? Or is this the twist of the summer?

They were beckoned out to the backyard for the first Head of Household competition. Sixteen globes were hanging from a suspension bridge above. "Your first Head of Household competition is simple. You will hold your globe on your back. When your globe falls off, you are out of the competition. The last person left standing will win Head of Household, get their own private bedroom, and nominate two people for eviction."

Callie chose a globe on the opposite side of the backyard from where Brandon's was, and positioned the globe on her back. "Ready...go!"

The globes were slippery, and round, and hard to hold onto. But she cupped her hands against the side of the globe and tried to make the best of it. She felt like Atlas, holding the whole world on her shoulders. She knew that if she won this, that an early target would be placed on her back, and she'd have to create enemies so fast. But at the same time, she'd be safe, and she could always make the really safe nominations. Someone always rubbed someone else the wrong way the first week. Always happened.

A few people fell out of the competition, and moved to the sidelines to finish watching. She looked around. She'd made it not quite halfway through, and it had been about forty-five minutes; her arms and back were beginning to kill her, and she didn't really want the power. Not this week, anyway, let someone else get first blood on their hands. Good of a time as any. She let the globe slide off her back and she stretched her back up. God, it felt good to be out.

"Callie, you are out of the competition."

Moving over to the sidelines, she sat down next to Joy. "Who do you think's going to win?" Joy asked. "I was cheering for you, if only because I'd get the bed to myself this week."

"Ha," Callie said, with a laugh, "I'm thinking it might be Evan. Or Brandon."

"He's kind of cute, isn't he?" Joy said. "Brandon, I mean. He has that whole tortured musician thing going on."

"Yeah. He is." Callie nodded and turned around just in time to see Brandon's globe slide off his back. "I guess he's not."

Lauren, one of the "interchangeable blondes" from outside, won the first Head of Household. As she swung the key around her neck and giggle, Callie had to stifle a groan. With her luck, this Lauren girl would be looking to target the other girls and keep around the guys as her arm candy. And she was clearly out of place among the girls. She saw Rebekah - Becks, she mentally amended - out of the corner of her eye. Okay, maybe she wasn't totally out of place.

The houseguests walked inside the house and went to the bathrooms to get cleaned up - there had been blue dye squirted on them during the competition, and they all looked a little bit like Smurfs. Some had gotten it worse than others. Lauren pulled her aside outside of the bathroom. "Storage room, fifteen minutes," she said, in a hushed whisper between gritted teeth.

Callie kind of wondered how she was supposed to tell when fifteen minutes was up, when there were no clocks or watches in the house, but she nodded anyway. "Okay."

"Bring your bedmate." And like that, Lauren was off to the showers, leaving Callie behind in a ball of confusion. She could get Joy to come, she was sure, but she wasn't sure what this was all about. Some sort of secret talk?

Brandon went into the storage room and made sure that the door shut behind him. Lauren had told him to meet her there, and he wasn't sure who else would be coming. No one else was there yet - apparently his estimation of fifteen minutes was either more conservative than accurate, or the others were too generous in their guesses.

The door cracked open, and Joy and Callie slipped in, quickly followed by Adam. "Hey, did Lauren tell you to come here?" Adam asked. "Because it was kind of weird, man, like, she was being all hush-hush and whispery and we don't need this on the first night."

The other three nodded, and then, almost as if on cue, Lauren came in and stood against the door. "Okay, so you're probably all wondering why I brought you in here."

"Yeah, just a little," Callie said. "You're Head of Household, shouldn't you be out there mingling with everyone?"

"If I wanted people to come kiss my ass, I'd do that. But I don't. I like you four the best, and you all did well in the competition - or somewhat. So I was thinking, we all look out for each other. I won't nominate any of y'all this week, and y'all won't nominate me if you win next week, and we're good with that?" Each of them nodded, and she grinned. "Great! We should have an alliance name."

"What about Full House?" Adam said. "A full house is three of one, two of another, and there's three girls and two guys in this alliance."

"I like it," Brandon said. "Reminds me of playing Yahtzee with my moms."

"So it's settled? We're Full House?" Lauren said. "Oh, this is so exciting! A first night alliance!" They joined in a group hug, and Callie looked up at Brandon, who was looking straight at her. She could only smile.

Callie (diary room): So I got roped into an alliance with Lauren and Adam and Brandon and Joy, and we're calling ourselves Full House. You can't say no to the Head of Household when they propose an alliance with you, that's just stupid. And...Brandon's involved. So I guess I'm happy.

As they drifted off to sleep the first night, the excitement dying down, Callie hugged her pillow tightly and listened to the sound of the pre-recorded ocean waves that were piped into the room. "Good night," Joy said, "sleep tight, don't let the bed bugs bite."

"If there's any bed bugs in this bed, they're biting your butt too," Callie said, closing her eyes and willing herself to go to sleep. This would not do, if Joy was a bedtime talker, because she was a bedtime sleeper. Not that she'd ever shared a bed with anyone who wasn't family, but she might just have to try to win Head of Household at this rate. Just to get a bed to herself again.

End Day 1.
