Title: Cleanse by Merlin_Wolfgang_Trades_Hale

Summary: After another supernatural-themed case, there's someone at the office who comes in to cleanse the team. Danny is skeptical and wants to get out of it, but the team won't let him. So he's cleansed. Big whoop, right? Actually yes. See...Danny was cursed when he was ten. There had been no way to reverse the effects so he got used to being a guy. So being a woman now was...weird. Even weirder are Steve's reactions.

Notes: Chloe Decker is who I see as a FemDanno. You can imagine whoever you want but that's who I'm imagining. I apologize in the constant switch between he/him her/she thing. It's gonna annoy some people and I am sorry.

"This is ridiculous, you know that right?" Danny muttered but was ignored.

The others took the cleansing seriously and did what was asked without question or fussing. Danny, of course, was Danny. When it came to the supernatural he always seemed to be the same about it. No matter how much rich history Hawaii had about being close to the spirits and deities of the island.

"Danny. Just...just go with it, okay?" Steve asked while rolling his eyes at his partner. He already had the lecture about respecting the culture set in his mind for the ride home.

Danny sighed and let himself be 'cleaned'. He didn't think it would take long and the worst would be that he couldn't get the smell of that incense out of his clothes. But something started to feel funny. He began to cough as a weird sensation spread throughout his body.

"Danny, stop being so dramatic. Go wait in your office if you really don't-Danny?" Steve stopped midsentence as Danny fell to his knees.

"Get him on his side," Chin said as he hurried to Danny's side. Between he and Steve they got Danny on his side, and Steve rubbing his back.

"What's happening?" Kono asked.

"An allergic reaction to the incense?" Chin guessed.

"Aunty, what's in that?" Kono asked.

"What's needed for a cleansing...and it worked." The old woman said.

"With all due respect, whatever you did is hurting my partner!" Steve yelled angrily.

"Not hurting." The old woman said as she pointed to Danny's now unconscious and female form. "Cleansed."

"It's...he's...what?" Chin asked, flabbergasted.

"Danny's a girl?" Steve exclaimed.

Chin and Steve seemed to be panicking. Chin more internally while Steve began to pace like a trapped animal. Kono looked at the older woman and asked, "What's happened Aunty?"

"My guess? Your friend has been cursed for some time...the cleanse I chose was very powerful considering the spirits you faced. But his body has been cleansed and now his true form is shown. We should get her someplace safe and more comfortable than the floor."

"You got a point," Kono commented. Now as a woman, Danny was smaller so Kono was sure she was lighter. But she didn't want to hurt Danny by moving him too much. "Steve." When Steve stopped pacing and looked over at Kono she ordered, "We need to bring him, uh, her? Back to hi-back to Danny's place. Can you pick Danny up?"

"Uh...yeah. Right. Yes." Steve said as he carefully picked his partner up. If he hadn't seen it happen before his own eyes, he might have more trouble believing it. But believing wasn't an issue. Right now Danny needed him, no matter what he was right now.

"Whoa, what are you doing?" Steve demanded of Max.

"Inspecting Detective Williams." He answered simply.

"Right." Steve nodded, placing his hands on his hips. "But uh...why...why are you...undressing hi-her?"

"This is a very unusual phenomenon. Even though Aunty has explained as best as she has, in medical terms this is...unheard of. But keeping my supernatural curiosity aside, I am merely checking to make sure that Detective Williams is unharmed."

"Right. Uh, yeah okay. You're a doctor. And you're...you're Max." Steve said, but more-so to himself. He stood guard and recrossed his arms over his chest and waited for Max to continue. He wanted to make sure Danny was alright too.

"Commander?"

"Yeah, Max?"

"Do you mind waiting outside?"

"Why?" Steve asked as he cocked his head to the side.

"You are not a medical official. I'm not sure Detective Williams would like to have you be witness to an exam."

"It's okay Max I..." But Steve stopped himself. Partly because of Max's strict look, but also because he realized that in this situation, maybe he should turn around. "I'll be right outside. Call me in if you need anything."

"Right."

Max began to examine Danny and that includes getting rid of Danny's clothing. There were wounds and scars, but from speaking aloud, Steve confirmed all of the injuries Max called out. They were either from a case or Danny learning to surf.

Well, almost all of them were explained. There was a weird mark on Danny's back. Max covered the lower back and he had Danny turned over as he called Steve in to look at it. But that was when Danny woke up with a gasp. Bolting up felt weird. His body had different weight than before and it took him a moment to get his bearings together.

"Steve? Max? What's goin-what's with my voice? Why's it so cold?" Danny asked as he wrapped his hands around himself and that's when he felt them. Looking down, he shrieked before pulling the blankets up to cover his body.

Danny then motioned with his hands, "What the hell do you guys do? What happened? Wh...oh fuck." Danny groaned as he buried his face in his knees.

"Good news Detective Williams. You seem to be okay. Other than that you have gone through quite the...extraordinary transformation. How do you feel?" Max asked with his typical, normal upbeat-ish attitude.

Danny raised his head and glared at them. "You two saw me naked."

"Yes well...uh...I'm a medically trained professional. And I was asked to make sure you were okay." Max said in his defense.

"Okay. You I believe. And forgive. But you." Danny hissed at Steve. "This is all your fault!"

"My fault? How the hell is it my fault?"

"I told you I wanted to go home, but you made me stay and get cleansed."

"Yeah, well...how was I supposed to know you'd turn into a woman?" Steve demanded.

"You could have just respected my wishes and let me go home!" Danny yelled.

"Uh...we hate to interrupt but, Danny...do you know what happened?" Kono asked as she and Chin and their old woman friend came in to check in on Danny.

Danny sighed, "I was born a girl. I was cursed when I was a kid. There wasn't a cure even though we looked for months. After a while, I just got used to being a boy. I made my peace with it. Hell, I went through puberty as a guy. That pretty much sealed the deal. I wasn't expecting to ever switch back! And now I'm naked in a room full of mostly my co-workers. Can I get some clothes, please?"

Everyone left the room and Kono came in to give Danny some clothes. They decided to go to the McGarrett home for the privacy and room, so the clothes that Kono had gotten were Steve's. Even as a man, they would have been big on Danny, but now they were extremely baggy.

"Why are you so sexy?" Kono asked, only half joking.

"Because I'm everyone's type," Danny replied without missing a beat. "Ugh...I haven't had hair this long since college."

"I'll see if I can find you an extra hair tie or a ribbon or something to hold it back."

"So...that's Danny huh?" Chin asked sharing a meaningful look at Steve.

"Yeah...holy fuck," Steve muttered as he closed his eyes to focus.

"I thought we already knew that was Detective Williams?" Max asked confused.

Steve and Chins shared another look with each other before looking back at Max.

"What we mean is that...uh..."

"Danny as a woman is...um..."

"Fine as hell," Kono said coming in with a smirk.

"Oh. Yes, Detective Williams is quite attractive." Max agreed.

"How is he? She I mean." Steve asked.

"Better than I expected. But if the story's true, then Danny's used to a change like this. So now we just have to talk about what gets gone." Kono replied.

"What do you mean?" Chin asked.

"Well, the Danny Williams we know is a man. All of his paperwork is as such. This will make crime fighting a bit complicated until we decide if we tell people or not. If this is Danny's true form, do we even bring up trying to turn her back into a man?" Kono asked.

Aunty had been on the phone speaking to some of her friends. She approached the group and said, "Turning him back is not possible. You would have to piss off a very powerful witch to curse him again...and the cleansing I did will protect him for at least a year."

"Alright, so what do we do?" Chin asked Steve.

"Uh...lemme go talk to Danny," Steve said.

He knocked and was pretty sure he could handle Danny once the door was opened, but he couldn't. When Danny opened the door to the bedroom while wearing his clothes...well his mind went to other places. Bad places that had his body reacting in a very inappropriate way right now.

"Hey..." Danny said gently, not seeming to notice Steve's lower region plight.

"Hey. Uh...stupid question. How are you?"

Danny let out a deep sigh. "You'd think I'd be used to weird by now. But this? This is a whole new level of weird. Again. This stupid curse was the only supernatural I've ever encountered. After my parents tried to cure me, we sort of did our best to avoid it. It was easier as a child...as an adult? Ugh, this is going to be hell."

"Maybe. But you're not alone." Steve promised.

Danny looked up at him and smiled. Out of an instinct, she went to hug him. Steve hugged back because of his own instinct. There was just a little problem with this hug. Or rather...a not so little problem.

"Uh Steve? Is that...?"

End Notes

I'm sort of on a McDanno binge. I'm going through a lot of tropes and ideas I want to be seen. The GenderSwap was next :) It also just goes hand in hand with JealousSteve & ProtectiveSteve trope that I love
