Jazz hadn't been feeling great for the past two decacycles. He was absolutely atrocious when it came to visiting Ratchet and taking his medical grade, as discovered when he had his virus, so it was a fight on Prowls part to get him to visit the medic. He had started to complain about a funny feeling in his spark, being more tired and always feeling hungry, as if something was draining him constantly and Prowl was starting to worry about his mate.

Prowl sighed when he couldn't focus on his work. All he could think about was Jazz and how worried he was about him – it obviously wasn't 'nothing' as Jazz insisted, there was something wrong with him!

So today, while Jazz was recharging, Prowl had taken him down to the medbay. It was worrying that Jazz had allowed himt o do that, as usually he was a light sleeper and being picked up would result in a punch to the throat. As he had learnt. The hard way.

::Prowl, I think you'd better get down here.:: Ratchet commed him. He didn't sound grave, as if Jazz was in danger of dying, he just sounded a little miffed. As if he were annoyed over something.

This gave Prowl some warning for the wrench that sailed past his helm when the doors to the medbay opened to allow him access.

"You fragger!" Ratchet snarled, another wrench already at hand. Prowl gave him a wary look.

"How is Jazz?"

"Oh he's fine, just one small little detail you should know."

"And that is?" Prowl was starting to feel a little nervous. What was Ratchet so mad about?

"He's sparked."

Oh. That. Surely he'd heard wrong.

"Excuse me?"

"With twins."

Prowl felt all of his weight sink down out of his body though his pedes. Jazz was sparked? When did that happen – no, how?! They'd been so careful-

"Twins?" Prowl replied weakly, feeling his processor starting to protect. Ratchet nodded, lips pressed into a firm line. There was a reason the medic was so pissed – He liked to be told when mechs were planning on having sparkling, especially considering he was the one who had to take care of them.

There was a distinct high-pitched whining noise, and Prowl promptly crashed. Ratchet sighed, picking him up and putting him onto a medical berth with the help of First Aid. Jazz was sat on another medical berth, watching the exchange with an expression of mirth. He was ecstatic. Sparklings! With Prowl!

Twins!

He'd always wanted to start a family with Prowl, however the war had put that plan on hold. They were in the high command – that made them targets already. A bonded couple? Even better. If one died, the other would follow. If one was tortured, so would the other one at no extra effort.

It was too dangerous to have sparklings.

This definitely changed things.

"Is he gonna be okay?" Jazz asked, walking over to the berth Prowl was in. Ratchet had hooked him up to something and was typing away on it, probably finding out what went wrong.

"He'll be fine. He's coming round now." Ratchet said, unplugging the device and glancing at Prowls face.

Jazz relaxed slightly – the crash wasn't that bad then. Before Jazz could excitedly greet him, Ratchet shoved a cube of medical grade into his hand.

"Drink it." He growled before looking at Prowl. "And you should know better than to fully merge with a high charge!"

Prowl looked at Ratchet blankly before slowly sinking back down into the berth and groaning.

"That wasn't a dream was it?"

Jazz quickly downed his cube with a grimace before piping up with a cheerful 'nope!' and hopping up onto the berth with Prowl. Prowl shifted to make room for Jazz, who snuggled up to his side.

Prowl could feel Jazz's feelings pour through the bond – happiness, admiration, love, nervousness and excitement. He felt bad about being so apprehensive over the thought of sparkling, however Jazz's excitement was contagious and soon Prowl felt himself warm up to the idea.

Ratchet had left them and given them some privacy while the black and white pair allowed the news to sink in.

"I told you that you should have seen Ratchet."

"Shh, you. Would'a been fine."

"You could have killed them, that is not 'fine'!"

"Ah was plannin' ta see Ratch today actually"

Prowl rolled his optics, sitting up and allowing Jazz to clamber into his lap, sitting across it sideways so that they were still facing each other. He nuzzled Jazz's audial horn, sighing.

"Don't ya want sparklin's?" Jazz asked, sounding worried. Worry and fear started to bleed through the bond, Jazz's excitement rapidly fading. Prowl pulled him closer, quickly kissing his forehelm.

"I'm glad there's nothing wrong with you. I thought you were ill again."

Jazz smiled, burying his face into Prowls shoulder.

The realisation that he was going to be a Sire suddenly slammed into Prowl. "I'm going to be a sire." He said quietly. Jazz nodded, grinning at him.

"Yep."

Prowl tightly hugged Jazz, sending al the adoration, love and excitement he could through the bond, kissing him passionately. Jazz returned what he could through the bond, and he was about to play with his mates doorwings before a wrench came flying over and smacked into Prowls helm.

"Not in my medbay!" Ratchet snarled.

Jazz laughed, jumping up from the berth and escaping, towing Prowl along behind him.

Thanks to MoonWallker for requesting!
