"I don't care if it wasn't professional" the neon green and yellow CMO snapped at his Prime as he prodded a sharp digit on Jazz's welds around his midsection making the immature saboteur giggle to his mate, who was wearily watching from a safe distance. "The slagging bot deserved it!"

"Ratchet, he was only offering advice" Optimus tried to soothe his irritable CMO only to get Ratchet's saw arm revving at him, teeth tipped liberally with Cybertrons hardest gem, rotating and glinting in the sun.

"Which wasn't wanted nor his to give" came the clipped reply "I'm the CMO, I know best"

"Yeah, well… knocking out the ARK's Ratchet wasn't exactly smart either" Mirage chuckled as Wheeljack tapped his data-screen, colour indicators rippling with rainbows as the engineer muttered to himself, tweaking virtual power routers and generally being oblivious to the world around him.

"Can we just move this into the ARK?" the boxier version of Optimus sighed as the pair of snickering Twins dragged the, knocked out, red and white Ratchet past the spikier dimension travellers, a dent in the poor medics helm from where his counterpart had thrown, or technically 'shot' a wrench at him from a compartment in the green and yellow mechs forearm plating after some snarky trading of relevant medical knowledge.

"Just give me a minute" the still online Ratchet growled poking his own dimension's Jazz in the stomach plating drawing forth a startled squeak from the TIC. "I need to make sure reckless and immature here doesn't literally split in half again"

"And why would you do that?" the ARK Jazz asked curiously, snickering as he saw both Prowl's begin to argue over the tactics of the battle a little way off

"Skippy here decided to take on Megatron by himself" Ratchet supplied "The stupid fragger got torn in half and nearly killed Prowl when their bond broke"

"T-t-torn in half?"

"Yeah, yeah, don't wear it out" the silver Jazz grumbled "I'm still alive ain't I? Ratchet performed some medic magic and the Jazz-man is back, truth be told, the Well is a bore. Did you know that Primus and Unicron play cards when they are bored?"

"Ha, you think we'll believe anything don't you Jazz?" Mirage sniffed "I'm still on the lookout for that rock you said was shaped like Starscream's head"

"Now that one is true!" the silver Jazz declared as they made their way back to the training room where they were currently 'hanging', as the Head of Ops said.

"Not to alarm anybody, but where's Wheeljack?" asked Ratchet, running a scan over the area in mild interest, giving a chirr of satisfaction when he saw the ARK Twins dragging the ARK Ratchet past the door.

The bots looked around them noting that indeed, their explosion prone Wheeljack was missing. "Aww, frag" Optimus grumbled "Autobots, split up and search, and try not to get in any of the ARK bot's way, find Wheeljack before this whole place goes up in an explosion"

"Aye, sir"

-Wheeljack's Lab-

"So I was telling him to have a little bit more faith in my abilities" Wheeljack explained to Wheeljack waving his data-pad around in mild frustration, his colour indicators flickering through all shades of red as the boxier version nodded in sympathy "I mean not all of my inventions explode, and the last incident was clearly Perceptors fault"

"Oh, tell me about it, Ratchet is always at my throat cables over my 'episodes' as well" the boxier mech replied with a nod, fiddling with a ball like doodad, his screwdriver half into the circuitry "However my worst Lab experience involved Fireworks, Dynamite and Sunstreaker's left pede. I had to hide for nearly a stellar cycle before I could come out of my quarters without fear of getting accosted by a furious, left pede-less frontliner."

"My worst one was when I left Perceptor in charge of a little pet I picked up on some planet or other, before coming to earth, luckily the atmosphere that it breathed was nearly identical to earth's. It was really cute, little fluffball was called Ted, looked a bit like a cats head with wings for audios and a long lizard tail, only about the size of a human. Anyway I foolishly let Perceptor look after him when I went on a mission. The small tyke got into Sunstreaker and Sideswipe's infamous 'Homebrew High Grade'. Next thing I know, he's expanded to almost Jazz's size and then he promptly exploded when Perceptor poked him." Wheeljack ranted subspacing his data-pad and taking interest "I really liked him too, though afterwards Prowl had a fit and sent the whole science team to clean him from the walls and roof."

"That sounds like a nutty weekend, but I'm sure I can trump you… let me get my data tracks…"

-Jazz's Quarters-

"I told you not to touch that mech!" the ARK's Jazz nearly shrieked at him as he fiddled with a few dials on the finely tuned stereo system upgrading it and slipping in a few new tunes into the already extensive library.

"Sorry" the silver Jazz shrugged as the wires slithered back into his wrists from linking with the sound system.

With an aggravated sigh the TIC of the ARK flopped onto his berth watching his dimensional counterpart explore his quarters. "Don't touch that either!" Jazz warned the black visored mech who extended a pointy digit to poke his gaming system that was innocently sitting on the shelf amid tape and video cases. He sighed and heaved his black and white frame up into a sitting position "Look, you share my name so we must have something in common…"

"Infiltrating bases and killing Decepticons?" the silver Jazz offered straddling his spare chair

"That's morbid"

"Force of habit"

"How about music?" the black and white Jazz asked curiously watching as the silver Jazz's face lit up.

"Mech, took you this long to get onto something interesting?" the four fingered mech grinned practically hopping in his seat "I'm the music master"

"Nah-uh" Jazz denied "Ultimate Music Master is decided by a game"

"… I'm listening"

"Alright here's what we're going to do" Jazz grinned leaning forward to conspire with his silver counterpart.
