A/N: yes this is a Thasmin Fanfic.

The Doctor quietly entered the expansive crystalline console room of her trusted TARDIS, throwing her long coat over on to the coat hanger. She strode over to the console, leaning on the glowing machine, looking up at the orange crystal in the centre as it moved up and down, pulsating like a beating heart. Beepings, whirlings and buzzings echoed from the glowing console as the Doctor played with the 'toy box' controls. The Doctor spun round the console, playing and enjoying every moment she got to control her magnificent ship.

Soon she came to a stop, she heard a tapping, the tapping of footsteps. Spinning, the Doctor came face to face with Yaz, who was still in her pajamas with her dark hair in a frizzy mess,

"Yaz! Hi, sorry!" The Doctor said in complete shock, holding her chest,

"What you doing up?" She asked quietly,

"Couldn't sleep…" Yaz groaned tiredly, a small yawn escaping as she spoke.

The Doctor smiled and looked at her sympathetically, placing her hands on Yaz's shoulders she said,

"Why?" She asked quietly.

Yaz looked at the Doctor then shrugged,

"I don't know, I was just thinking." She said quietly,

"About what? Honestly, humans are so cryptic. I'm thinking, great, what about?" The Doctor complained, scrunching up her face, only half joking. She was trying to lighten the mood, but it wasn't working if the expression on Yaz's face was any indication.

The Doctor took her hands of Yaz's shoulders and tapped her fingers on her legs,

"Why don't we...go to the pool? Pools are calming right? Yeah...maybe...I think so?" She asked, obviously only thinking of the second half of her initial question as she said it,

"What?" Yaz asked in mild surprise,

"Pool party! Me and Yaz! Just the two of us!" The Doctor explained enthusiastically, creating various confusing hand gestures before settling in a double thumbs up. Yaz was obviously confused but soon understood,

"Okay...what about Graham and Ryan?" She asked,

"Oh they'll be fine! Sleep like logs." The Doctor cheerfully retorted,

"Now you go get dressed and then we'll find the pool." She explained as she pulled her trench coat on. Yaz simply nodded and returned to her room to change.

The Doctor leaned on the wall outside Yaz's bedroom with her arms crossed over her chest,

"You alright in there?" The Doctor asked awkwardly,

"Uh...yeah…" Yaz replied with uncertainty in her voice but the door soon opened, revealing Yaz dressed in a simple one piece swimsuit and a towel over her shoulders. Yaz looked the Doctor up and down, smirking,

"Time lords don't believe in swimwear?" Yaz asked sarcastically.

The Doctor rolled her eyes and beckoned for Yaz to follow,

"So...where is the pool?" She asked,

"Somewhere. The TARDIS sometimes reconfigures her interior, sometimes the pools in the library, sometimes it's in the cricket field." The Doctor explained as they walked, approaching a large metal door,

"In the library?" Yaz chuckled,

"Yeah! She likes it that way." The Doctor smirked as the door opened to reveal a large tropical landscape at the center of which was situated a large, lavish pool. It actually looked like it had been landscaped more than built. Yaz could see all the way to the bottom through the crystal clear water and noted that it looked like it was covered in smooth, rounded rocks, like on the bottom of a river. One end of the pool sloped into the water like a beach. In fact, there was even sand, though it didn't seem to be stirred up at all by the water. At the deep end, there was a large boulder set against what appeared to be a three-story-tall cliffside. Water flowed down a smoothly-carved groove in one side of the boulder, emptying into the pool, looking for all the world like a water slide. The other side had a bit of an overhang, as if mimicking a diving board. Stairs were carved into the cliffside leading to the top,

"This is so cool!" Yaz said happily as she threw her towel at the Doctor, running and diving into the pool instantly. This caught the Doctor off guard but she placed the towel on a side table alongside her boots and socks. Sitting on the edge off the pool, she pulled her trousers up to her knees and kicked her legs in the water, just watching Yaz swim towards her, leaning on the edge with her elbows.

They both looked at each other, the Doctor just looked like her childish self, but Yaz looked inquisitive,

"I was just thinking, how'd you hold your breath so long? Back with King James?" She asked.

The Doctor looked up the told Yaz to sit on the edge, which she did. Suddenly, the Doctor jumped into the large body of water with a great splash. Yaz nearly dived In after her, but noticed the Doctor floating to the bottom of the water, soon sitting cross-legged on the bottom of the pool. Yaz exams the Doctor's calm demeanour with confusion, but caught a glimpse of a strange movement around the Doctors diaphragm,

"Doctor? It's alright to come up now!" Yaz called down to the Doctor, who returned with a large grin as she pushed herself up to the surface of the water, floating on its surface,

"Observations?" She mused,

"Apart from the weird diaphragm thing?" Yaz replied,

"Points for Yaz!" The Doctor started,

"My people have a cheat, a Binary Vascular System, lets us recycle a breath for a while, not forever though." She explained as she floated towards Yaz,

"That's pretty impressive…" Yaz said in genuine amazement.

The Doctor hopped up and sat bedside Yaz with a big grin,

"It's simple biology really!" She said with enthusiasm. Yaz chuckled softly and wrapped an arm around the Doctor,

"Not really, you're an alien to us." Yaz said, not noticing the Doctors awkward expression,

"Y-Yeah… " the Doctor murmured, Yaz finally noticing the Doctor's expression and removing her arm,

"Sorry…" Yaz said quietly,

"No it's fine! Really! I just...Well you know…" the Doctor tried to explain,

"Well I...I like….I like…" The Doctor was at a loss for words as Yaz simply looked at her with a confused face,

"I LIKE YOU!" The Doctor shouted but immediately covered her mouth with her hands. Yaz just say there, mouth and eyes wide open. The Doctor looked down and hid her face in her hands, Yaz felt immediately sorry for her and wrapped an arm around the Doctor,

"Hay it's okay! Look, what do ya mean by 'like'?" She asked quietly. The Doctor revealed her blushing face and looked at Yaz,

"Like...when you...wanna...get to know someone...better?" The Doctor attempted to explain. Yaz burst out laughing, hugging the Doctor tightly, which in turn sent the Doctor into some sort of fearful feital formation,

"Why didn't you tell me sooner?" Yaz asked, looking down at the Doctor's blushing face,

"Well...I tried...google didn't help. Said things about building nests and decorative feathers. So then I asked Graham and Ryan...they didn't help at all...it was...annoying." She admitted nervously, looking down. Yaz immediately smiled and kissed the Doctor's forehead, which made the Doctor glare at Yaz in complete and utter shock. Yaz smirked and brushed some of the Doctor's blonde licks behind her ear,

"Just...ask me next time...okay?" Yaz asked with an adorable smile,

"Okay…" The Doctor replied quietly, and the two hugged all night…we'll theybgot dry first...then hugged...and watched movies...and ate chocolate...
