Toothiana stretched with a yawn as she awoke, looking around curiously. She smiled and stroked Baby Tooth gently as the tiny fairy dozed on the pillow next to her, for all intents and purposes, mother. As the haze of sleep wore off, Tooth snapped upright, sitting up suddenly and looking around in alarm. "That's odd... Where are we? And what was I doing asleep? I almost never sleep, especially not that deeply...", she muttered to herself as she stood up from the bed. Upon her feet touching the ground, Tooth's wings automatically sprung into action and she was soon hovering in the air. As Baby Tooth started to stir, Toothiana picked her up gently and cradled her in her hands. "You alright, Baby Tooth?" The tiny fairy nodded with a squeaky chirp which caused Tooth to smile in relief. "Oh good." When a knock sounded out from the door, Tooth jumped in surprise and clutched Baby Tooth to her chest protectively, calling out nervously, "Who's there?"

The door opened and a person's head poked in. "I am the Fact Droid. Greetings"

Tooth waved politely, but nervously. "I'm Tooth. Nice to meet you. Umm... Not to be rude, but since I can tell you're not quite human, what are you exactly?"

The man opened the door and stepped into the room. He had the appearance and build of an average thirty year old man, wore a lab coat and purple tie with jeans and sneakers, had wire-frame glasses with round lenses that covered green eyes which almost seemed to glow, and had black hair which was slicked back. He gave a smile. "The Fact Droid is not defective. Its facts are wholly accurate, and very interesting."

The statement caught Tooth off-guard as she blinked in surprise. "Oh dear..."

Not noticing his companion's response to his previous odd statement, the Fact Droid continued on. "The square root of a rope is a string."

Tooth gave a sigh and whispered to Baby Tooth, "I think the Fact Droid might actually be defective..." Baby Tooth gave a squeak in response as she shrugged, and only Tooth could understand the little fairy's chirping language.

"89% of magic tricks are not magic. Technically, they are sorcery", the android stated, his expression and voice indicating that he was completely serious.

Tooth stared at him, totally nonplussed. "I'll take your word for it. Say... Could you tell me where we are and how we got here?", she asked while motioning to herself and Baby Tooth who was now perched on her shoulder.

The Fact Droid nodded brightly. "Fact, you are in the Aperture Science Enrichment Center."

The Tooth Fairy tilted her head to the side contemplatively. "I see. …. No, I don't..."

"Fact, space does not exist", the android chimed brightly.

Toothiana face-palmed. as she muttered to Baby Tooth, "Now I know he's defective..."

"Contrary to popular belief, the Eskimo does not have 100 different words for snow. They do, however, have 234 words for fudge. The first commercial airline flight took to the air in 1914. Everyone involved screamed the entire way", Fact Droid continued on.

Tooth paled and turned slightly green at the last statement. "Oh dear Moon..."

Unaware of the fairy queen's discomfort, the android kept rambling on. "Fact, GLaDOS has been known to lie. The situation you are in is very dangerous."

Toothiana bit her lip to hold back her giggles before whispering to Baby Tooth who was perched on her shoulder. "If this is dangerous, I hate to see what he calls real danger. Though, I wonder who GLaDOS is... I've never heard that name before. Have you?" When Baby Tooth chirped and shrugged helplessly, Tooth gave a shrug of her own. "Oh well. If it's someone that lives around here, I guess we'll find out soon enough..."

"Gently cleaning the tongue twice a day is the most effective way to fight bad breath."

Tooth blinked in surprise before grinning. "I've heard that said before, yeah. Do you know anything else about teeth?"

The Fact Droid nodded with a friendly smile. "I do. An average person has 32 teeth. That number includes 4 wisdom teeth. They have 8 incisors, 4 canines, 12 molars and 8 pre-molars. A person gets two sets of teeth over the course of their lifetime."

The amiable fairy queen gave a happy nod of agreement. "That's all true. What else do you know?"

"40% of people over 65 years of age do not have all of their teeth."

Tooth gave a soft gasp. "Oh dear... That's not good..."

Fact Droid nodded. "Certain drugs will prevent you from being able to have teeth pulled."

Both fairies blinked in surprise and tilted their heads quizzically as Toothiana spoke up. "I didn't know that... I wonder what kinds..."

The friendly android shrugged. "That I do not know."

Tooth eyed the android thoughtfully. "How do you know so much about teeth anyways?"

The droid smiled. "I am a Fact Android. I generate facts."

"Do you have a name?"

The dark haired android shook his head. "No, I do not. Should I?"

The fairy queen stared at him thoughtfully for a moment. "Everybody has names. Hmm... You look like a Harold to me! I'll call you Harold!"

The newly dubbed Harold thought for a minute before smiling. "Alright then. Harold it is. Each tooth is attached to your jaw socket and has blood vessels and nerves. 2/3rd of the length your tooth is in the gum."

Toothiana grinned and nodded in agreement. "That's right. Do you know anything else?"

Harold gave a happy nod. "An average American spends 38.5 days brushing their teeth over a lifetime! Colgate Total toothpaste is the best selling toothpaste in the United States."

The tooth fairy froze and blinked in surprise for a moment before clapping happily. "Really? Wonderful! That's wonderful!"

Encouraged by his friend's cheerful reaction, the android piped up with another random fact. "9 out 10 experts agree that dying is fatal."

Toothiana laughed. "Well the one who disagrees would be right. My friend Jack died and was brought back to life."

Harold looked at her quizzically. "Jack? Jack who?"

"Jack Frost. He's a very good friend of mine."

Thinking for a moment, the android piped up. "Jack Frost is the personification of frost and cold weather, a variant of Old Man Winter held responsible for frosty weather, for nipping the nose and toes in such weather, coloring the foliage in autumn, and leaving fern-like patterns on cold windows in winter."

Tooth giggled and nodded. "That sounds more or less like Jack. He's not an old man, though. He's about eighteen or so, physically speaking."

Harold froze in surprise. "Real?! Jack Frost is real?!

Tooth laughed even harder. "Yeah, he's real alright."

The android paused for a moment. "Hmm... Looking up data from Test Subject Records... ... Fact, Jack Frost is in love with the Tooth Fairy."

Toothiana blushed heavily and froze on the spot. "Wh... Wha... What?!"

Before she could react any further, another voice spoke up over the comm system that ran through the facility. "I am glad to see that you have finally woken up, Test Subject. My sensors indicate that your vitals are stable. Very good. If you are ready, we can begin testing immediately."

Tooth reached up to pet Baby Tooth soothingly as the little fairy shrieked in alarm and landed on her shoulder to cuddle into her neck, shivering heavily with fright. Throwing an uncharacteristic glare at the wall for startling her little one since she couldn't see the actual owner of the voice, GLaDOS, the feisty fairy queen spoke up. "Testing? What do you mean testing? What are you testing me for?" Though she'd been attempting to sound bold, Toothiana's voice carried a note of wariness and uncertainty. Part of her wasn't so sure that she wanted to know what the testing was for.

Before the Tooth Fairy Queen could reconsider her question, though, GLaDOS started speaking in answer to it. "It is in my programming to test Aperture Science products, especially the Aperture Science Hand-Held Portal Device. That is where you come in. All you must do is follow the hallway to the testing tracks and solve the tests. Once you are finished, you are free to go."

Hearing the click of the comm connection being cut, Toothiana looked around and fluttered over to the door when she noticed it. Before she entered the hallway, she poked her head out the door cautiously to look around. Since she didn't see anything dangerous, she zipped out into the hall with Baby Tooth and Harold following her. The three of them traveled down the hallway in the direction that Harold indicated they should go to reach the testing tracks. When the trio reached the door, Tooth poked her head inside and looked around warily again. Harold whispered a warning to her. "Fact: GLaDOS' tests have been known to be very dangerous..." Tooth gave him a nod to show she heard him and then slipped inside.

The inside of the test chamber was relatively simple. The room was mostly barren aside from two buttons and a switch on the ceiling, the doors, a dispensing tube and an orange traction beam. When the door that they walked through automatically closed behind them, the three jumped in a brief moment of startled fright. As Toothiana looked up at the ceiling, wondering what everything was for, Baby Tooth zipped up and poked at one of the buttons with her tiny hands. When she accidentally pushed the button, a loud rumbling was heard for a short moment as a metal cube tumbled out of the tube and fell to the floor with a heavy clang and thud. The sudden commotion caused all three of them to jump a bit due to being startled by it. Once they recovered, however, Tooth glanced from the cube to the switch thoughtfully. Making note of the button Baby Tooth had pushed to make the cube fall, Toothiana flew up to the other button and pushed it tentatively. This caused the traction beam to reverse directions and turn blue in color. When Harold saw that the beam was now heading towards the switch instead of away from it, he pushed the cube into the beam and watched with a grin as the cube was carried up to the switch.

As soon as the switch was pressed by the cube, the doors on the other side of the room opened and GLaDOS' voice rang out through the chamber as she spoke over the comm system. "Congratulations on solving the test. Well done. Please proceed to the elevator which will carry you to the next chamber so that we may continue testing." Deciding it would be easiest to just go along with instructions instead of arguing or questioning, Toothiana shrugged and followed Harold to the elevator with Baby Tooth sitting perched on her shoulder.

The trio walked down a metal staircase and into a small circular room with an elevator shaft and elevator right in the center. Just as they were about to step into the elevator, a small sniffling sound echoed through the room which made Toothiana stop and look around as her maternal instincts flared up. Huddled against the wall behind the elevator was a little girl who looked about ten years old and had black hair that hung to her shoulders. Tooth made her way over to the girl and knelt down next to her, gently laying a hand on her shoulder. "Hey there, Little One. What's the matter? Are you lost?" When the girl looked up at her with watery eyes and nodded timidly,Tooth gave her a warm and reassuring smile. "It's alright. Why don't you come with my friends and me? Maybe we can help you."

The girl looked between them all for a moment, sizing them up warily before deeming them safe and nodding with a small smile. "Okay... Thank you..." She stood up with Tooth and held her hand as they walked over to join Harold, the Fact Droid, and Baby Tooth.

Tooth held her hand and smiled down at her. "It's no problem at all. Do you have a name?"

The girl nodded. "Most people call me the Curiosity Droid, but some of them also call me Virginia."

Tooth gave a soft chuckle as she led the small group into the elevator. "Virginia it is then."
