You'd think there'd be more work for these two, but oh well, here I am paddling the canoe. And this particular breed of plot bunny has been hopping around my brain for a few years now, and this prompt gave me a good idea (the day of, which is why it's posted late, but better late than never).

MAJOR DISCLAIMER: I am not trans. I've never questioned my own gender identity, and the only trans people I know are online. So if anything about this fic is offensive, please let me know so I can do better next time.

Jack couldn't keep himself from pacing, wondering if this really was a good idea. He'd have to tell her at some point, and he'd already invited her over to talk about it, but was this really the right time? Maybe he could pretend-

The ringing of the doorbell cut off his train of thought, and he listened as Miko spoke with his mom for a minute. He took a moment to calm himself and turned just as she stepped into the doorway, an arm holding onto the door jam.

"Hey Jack. Your mom said to keep the door open." She rolled her eyes but was smiling. "What'd you wanna talk about?"

"Hey Miko. Could we maybe… sit down?" He gestured to his bed, which was the only place to sit besides his desk chair.

Miko raised a brow, but headed over, sitting crisscross at the foot of the bed while he sat at the head. "What's up, Jack?"

Jack took a deep breath, and stared at the wall over her shoulder. "I've got… a big secret to tell you. And I'm not sure how you'll react to it."

"What kind of secret? You're not dying, are you?" Her voice wavered slightly, and Jack was quick to reassure her.

"No, no, nothing like that." Just rip off the bandaid. He took another breath, and said "I'm trans."

Miko blinked at him a few times "Oh." A moment's silence. "So am I dating a boy or a girl?"

Jack was stunned, but managed to stammer out. "A- a boy. I'm a boy. I thought-"

"You thought I'd go all crazy about it?" Miko shrugged and smiled, then reached for his hand. "Yeah, I get why. But this is more personal than the 'Bot stuff. I won't go crazy until you say it's okay, and only the good kind."

Jack smiled, and couldn't help the tears that slipped from his eyes. "T-Thank you. Thank you."

"Hey, no crying about this, it's a happy moment." She crawled up to him and wiped the tears away, kissing his cheeks on each track, then a few more times, louder and messier until he laughed and pushed her back. "So, who else knows?"

"Mom, she's the first person I ever told. And Arcee knows, I had to tell her when my period hit while we were riding, and she thought I got cut by something on the road." And technically his dad, but considering he left rather than deal with having a trans son, Jack didn't count him.

"Oh, you're the one who stocked the large overnight pads in the base bathroom. I thought that as Fowler or your mom." Miko leaned against his side. "You're not on any drugs?"

"I only became eligible this year, and we can't afford it, even with Mom's insurance." He shrugged. "I'm doing alright, though. School has me down as a boy and I change in the stalls, and no one bugs me besides Vince, and he doesn't get physical. Long as I got my packer and binder, I'm good."

"So you're not just happy to see me," Miko smirked and poked his leg, where said packer was resting. "Wait… You're only supposed to wear binders for a few hours, right? How long have you worn yours today?"

"Uh… all day? Hey!" He ducked down as Miko swatted his arm.

"You dum-dum! What would your mom say if she knew you were overbinding or whatever the word is?" She pushed him until he stood up, then covered her eyes. "Take it off, and then come here and cuddle."

Jack sighed. "Alright, you win." But he couldn't help the smile that crossed his face. Miko wasn't disgusted or mad or upset. It felt like a whole weight had lifted off of him, and had nothing to do with the binder coming off to let his breasts hang free. He pulled his shirt back on, and didn't feel self-conscious when he said "Okay, you can open your eyes now."

Miko did, then made grabby hands at him. He obligingly came over and laid down on the bed, Miko flopping on top of him with her head on his chest and their arms around each other.

"Thank you for telling me, Jack."

"I figured I should, before, uh…"

"Before I tried to go down on you and got a surprise?"

Jack flushed. "Some- Something like that."

"You gonna tell the team?"

"Yeah, sometime soon."

"Good."

The two lounged in the silence for a minute, before Miko spoke again.

"Would it be transphobic or something if I teased you a little?"

Jack chuckled. "I'll let you know if something hits too close, but if you didn't do a little teasing, I'd be worried you were sick or a pod person."

"Good, then why the heck are you a guy, but got bigger tits than me?" She poked the side of one of his breasts in emphasis, and Jack laughed and poked her back.

This had been a good idea.
