"Sydney…I don't want you to be furious. I have kept many secrets from you in the past…And now, it's time to reveal one of those secrets." Jack Bristow began as his daughter, Sydney Bristow, sat across her designer couch, her heart racing inside her chest. She was scared about what Jack was about to disclose.
"Go ahead…" She whispered. Jack sighed.
"Your mother and I….we…we had another daughter when you were only two, so you wouldn't remember. The reason why I kept this from you…it's complicated to explain why." He finished. Sydney was distraught. Another big secret kept from her. Sydney gulped.
"Where…where is she now?" She asked, hoping to receive at least some good news that her and Nadia's sister was alive, out there somewhere. Jack sighed, looked down, then back up with a pained expression.
"That's the problem…We have no idea where your little sister is."

Tara Byrne silently logged off her computer, closing up her CIA office for the rest of the night. She packed her suitcase full of her belongings, such as a hairbrush, important documents and papers, folders with assignments, and all that other neat stuff. As she wrapped up packing, a figure silently approached her desk, undetected. The figure then reached out a hand and tapped Tara's shoulder, making her nearly jump 10 feet in the air. "GAH!" She yelled, whirling around to face her 'attacker'. Her 'attacker' ended up being Jack Bristow, but could barely recognize him due to the dim light they stood in. She brushed her red-hair behind her ear and glared. "Give me a heart attack, will you?" She snapped at the gray-haired man, brushing her shoulder off. Jack wasn't amused. Instead, he asked the strangest question a well-known, serious agent could ask.
"Do you share your hairbrush?" Tara raised an eyebrow, and looked at Jack like he was the dumbest person on the face of the planet.
"My hairbrush? Uh…No…." She said with caution. Jack nodded.
"Good. May I borrow it?" He asked. Tara widened her eyes. Surely, she thought, he must be joking.
"Uh…Sure…" She muttered, pulling the pink hairbrush out of her bag. "Here…" Tara handed the special agent the brush. He smiled, satisfied, as he looked at the girlish object in his hand.
"Thank you, Agent Byrne. It will be returned shortly." He replied, spinning around and walking away, leaving Tara standing at her office desk, wondering why the great Jack Bristow would want with a pink designer hairbrush.

Sydney sat on her couch late at night, flipping through her phone contacts out of boredom when she noticed a number that seemed to stand out from the other numbers. Her sister, Nadia Santos's, cell phone number.
Your mother and I had another child.
The minute she laid her chocolate brown eyes on that number, the same thought replayed over and over in her head. She felt a little dizzy, and used her hand for head support. Should I call her? Tell Nadia about our missing sister? Sydney made a decision. She clicked on the number, pressed DIAL and held the phone up to her ear and listened to the phone ring over and over again in her head until a small, tired voice picked up on the other end on the phone line.
"Hello…?"

Nadia Santos yawned, too tired to be interested in what Sydney was saying. She continued to pretend to listen, occasionally a 'Yeah' or 'That's nice' on the road, but snapped awake when she heard the words 'We have a long-lost missing sister.' She walked over to her sofa and sat down to steady herself from the breaking news that she just heard. "Have you heard anything else about her?" Nadia asked, hoping for the same thing Sydney had hoped for when Jack told her. Sydney sighed and sounded stressed.
"No…Nothing…" She said, almost in defeat. Nadia frowned.
"Please, Sydney, let me know when you find something out about her!" She begged. Sydney groaned.
"I…I will, alright? I promise." She said. Nadia nodded, forgetting that Sydney couldn't see her nod.
"Alright…Thanks, Syd." She said, pressing the END button and letting the phone fall into her lap. Nadia rubbed her temples. Life was difficult with these type of things.

Tara sat on her friend's bed, cross-legged, sipping on Mountain Dew from a straw while listening to Celine Knight's famous lecture about the latest gossip in the CIA. Tara felt like she was in high school all over again. "So…" Celine began. "I heard something about Sydney and Nadia having a long-lost sister. Weird, huh?" Tara nearly choked on her drink. Celine was alarmed. "Woah, Woah! Take it easy Tar!" She said cautiously. Tara gasped for air then turned to her worried friend.

"That's why..." She whispered. Celine raised an eyebrow.

"Excuse me?" She asked.

"Jack...The hairbrush...Lee, I have to go." She said, getting up and walking into the kitchen, grabbing her coat and car keys, and heading towards the door, her friend close behind.

"Why?" Celine asked demandingly. Tara stopped at the door.

"Reasons." She said without turning around and left.

Tara sat on a nearby park bench, nervously checking her watch once in a while. It was almost midnight and her 'contact' was late."Where is he?" She hissed to herself. Once in a while she had to hide from passing policemen and ignore the creepy night crawlers on the nearby tree. It was hard for her. Tara sighed and looked down. He probably wasn't coming. She got up and was about to leave when she heard leaves crunching under someone's feet behind her. Tara spun around to see Jack Bristow walking towards her.

"Your right about everything," He began. "I needed your hairbrush because I needed something with your DNA on it. I gave the sample to Marshall, who traced your DNA to a matching file. Tara…Your not who you say you are." Tara's heart skipped a beat. "Then who am I?" She asked. Jack smirked and pulled her into his arms.

"My long-lost daughter, Tara Bristow."
