Ok this is the first flashback drabble, it takes place during Episode Nine when Duo and Heero were posing as students, enjoy!

After Colony 195

Heero did his best to ignore his temporary roommate and fellow Gundam pilot as the energetic teen kept ribbing him about Relena's surprise arrival in the aftermath of their basketball game. Really, why he found Heero's discomfort so amusing was quite simply lost on the young man, and he decided to voice as much.

"Duo, aside from you obviously enjoying the sound of your own voice, why are you so fixated on my current situation?"

His companion grinned while letting out snicker, "Gee, the girl who you were threatening to shoot in the damn face, was saved by yours truly, then proceeded to bandage you up after the fact hunts you down halfway across the world and your only response to her arrival is a blank stare. Now, I'm not one to beat a dead horse-"

"Yes you are," Heero seethed in annoyance.

Duo continued as if he hadn't spoken, "-but in the circles I run in 'I'll kill you' is not a phrase one usually uses to show their interest in a young lady."

"I'm not interested in her Duo," his companion further perplexed him by nodding in agreement.

"Obviously, you may feel oddly protective of her for reasons that elude you, sure, but showing actual interest in a romantic relationship, nope. So that begs the question, why is she stalking you across the world...and how...the how is what has me a bit lost..."

As they arrived at their dorm Heero let out a huff that seemed to confirm his own interest in this question as he slid his card key across the reader.

Door opening he turned to Duo while raising a single brow, "I have no idea and that is..."

"Disturbing?"

"Concerning," Heero corrected as he pushed the door open soon followed by Duo who rolled his eye while slamming it behind him.

"Yeah, to-may-toh, to-ma-toh, ugh whatever. Anyway dibs on the shower, I wanna get cleaned up and do a recon on the base before we proceed to make it all explodified. Wanna make a bet on which one of us wrecks it first?" With that he shucked off his shirt, and as Heero glanced up to respond he made a choking noise when he saw Duo's chest.

Duo for her part frowned at her fellow pilot as she tossed her shirt into the dirty clothes hamper, digging through her dresser she glanced back at the still wide eyed young man who was now making a high pitched noise audible only to dogs.

"Dude, what's wrong?"

Her voice seemed to finally snap him out of his reverie seeing as he quickly pointed at her sports bra clad chest, "You're a girl!"

Duo really didn't know what to say to that at first, either being insulted that she apparently wasn't feminine enough to be recognized as a woman, or complemented that her disguise was so well done that mister perfect soldier hadn't noticed.

She decided to go for the middle ground.

"You're a dork you know that right?" Heero just dropped his arm and tilted his head to the side still staring at her exposed torso, now feeling self conscious she pulled on a t-shirt and fell on her bed.

"Why?" He eventually asked, Duo began rubbing the sides of her head feeling a migraine coming on.

"Why what?"

"Why are you pretending to be male?"

At that she let out a disparaging snort, "Have you ever actually had to hang out with teenage girls for an extended period of time?"

Heero shook his head in the negative, "Outside of interactions during missions no, and that's involved you shooting me twice and Relena's apparently innate stalking abilities."

"You broke up Deathscythe to steal parts I would have given you asshole!" She spat back in annoyance.

"You shot me twice."

"Just grazes, didn't count, and besides I broke you out of jail afterwards so meh, even."

Heero kept shooting her a cockeyed look before he finally replied, "You've been pretending to be male much longer than our current mission, haven't you?"

Her face clouded over a moment before kicking her legs out quickly landing on her feet, turning to her dresser she grabbed a change of clothes and walked towards their small bathroom.

Heero thought she was going to ignore him further but eventually she sighed and dropped her head in resignation, "Solo always told me it was safer for pretty little girls to pretend they were little boys if they were going to survive on the street. He wasn't wrong, and I have no regrets following his advice."

With that she slammed the door behind her leaving Heero to his now confused thoughts.
