Optimus shuddered as he woke up, a cry on his lips. Not of pain but fear. First Aid was next to him in a sparkbeat, the young bot rubbing his back and holding his hand as Optimus came too, his vents working heavily. He had dreamed of Megatron, the first time they had met. The first time Megatron had almost killed him.

"Orion?" First Aid murmured, "Are you okay?" he frowned, Orion feeling a medical scan running over him, not from First Aid but from Hook, who had moved over to them as well. The spark monitor wasn't suggesting Orion was in pain but he was trembling.

"Nightmare," He smiled weakly at First Aid, "That attack hurt, a lot" He vented, his shaking slowly calming, his hand rubbing at his chest plates. Hook past him some medical grade energon, the Contructicon watching him with careful eyes as he took a shaky sip. Optimus shivered at the intensity of Hook's visor on them. "Was there an earthquake during my attack?" Orion asked frowning as he went through the memories of the incident, trying to distract them slightly.

"Yes, strange and we don't know why," First Aid commented frowning, "There is nothing recorded that would suggest why Cybertron would shake."

Optimus froze for a moment as something flashed over him. A memory of a datafile. Not one Orion would have known upon awaking up, something only Optimus Prime could know without looking in the Hall of Records. He knew what had caused the earthquake, and it was not a good thing.

"Orion?" Hook said in an oddly tender voice, "Is there something you need to tell us?"

Orion shuttered this eyes innocently, "I don't know what you are talking about," he said guardedly, Optimus cursing inwardly. It would be Hook who noticed him freezing, one of the few cybertronian's in existence who had been reformatted themselves. Who knew what it felt like to have strange memories which didn't fit.

"Orion…" Hook trailed off, "I'm not stupid. What came to you?"

"Just," Orion rubbed the back of his helm in a very human gesture that he had 'picked up' from the other young mechs who were currently awake. "Strange memory purges," he admitted, knowing Orion would not fight telling one of the medics that type of information. Optimus was not about to reveal the truth to them, but maybe it was time to take a few more risks with how much information he gave out. After all, if what he thought was happening was actually occurring, he would need to reveal his presence at some stage.

"Can you explain more?" Hook pressed, First Aid connecting Ratchet silently.

"When Aid mentioned that no one knew why Cybertron shook, I remembered my first dream with the statue I couldn't hear," Orion admitted, "And then Bluestreak talking about the festivals around this time of Vorn which every major city had. A datafile appeared aswell. Hall of Records stuff that I know you don't want me know."

Hook and First Aid both froze at those words. "We don't want you know?" First Aid clarified, "No such thing." The younger mech tried to laugh the word off, but it was obviously nervous laughter, "Why would there things we don't want you to know?"

"I'm not from Vector Stigma. Or rather, not recently. I was reformatted," Orion stated firmly and without care of their reaction. Optimus grinning to himself as the two mech practically fainted. First Aid stammered words out panicky while Hook just calmly stood there waiting for Ratchet to appear. Orion kicked his legs idly, "I don't remember who I was but it's the only explanation for a lot of things. It's why I don't like Prowl and Jazz. It's why my spark and frame don't match. Most of all, it's why I just had a nightmare of dying with very painful memories. Physically painful. You don't get pain in memory purges unless you have actually felt it."

That statement made both gestalt mechs freeze, along with their brothers. Optimus Prime had died? Hook took a step forward and pushed Orion down so he was laying on the berth. Gently, but with little warning, Hook opened his chest plates. First Aid moving close to look too, Orion letting them, more than a little surprised by their reactions. Hook didn't ask to see Orion's spark, nor did Orion unlock his spark chamber. Instead, Hook focused on the casing, hands trembling as he saw it.

Scaring from a gun, the type of scarring which came from a direct hit. Something which as far as Hook knew had never happened to Optimus Prime and yet it was there. Along with a memory of being shot.

:Megatron?: his link asked, First Aid falling to his knees beside him. The idea that Optimus Prime had been killed at one stage of the war almost too much for him to handle. There had never been any rumours or stories of Optimus Prime being felled, and Megatron would have shouted any times he had done so to the high heavens.

"What do you remember of the mech you shot you in your dream?" Hook asked, his voice barely steady. He had been expecting Optimus to return after a spark attack and possession by Primus. Not this.

"Silver. Red eyes. He had a cannon," Orion paused, closing his plates, Hook letting him. He had seen all he needed to. Orion rubbed his chest again. "I remember my spark feeling funny when I saw him. I opened a door and he was there. Then he shot me."

First Aid, who had just pulled himself up, collapsed again as he heard those words this time blacking out. Hook was not sure how he hadn't crashed himself at that news. Orion looked at the two of them concerned, shifting to get off the berth to help First Aid, but Hook stopped him. A hand on his chest, the Decepticon shaking his head.

"No, stay on the berth," Hook ordered, kneeling down himself to pick up First Aid. Putting the junior medic on a berth and checking him over. His mind refusing to think about the secondary information he had just been given. Megatron had shot Optimus. The chances of it being anyone other than Megatron was low but how had none of them noticed it?

"Have I done something wrong?" Orion asked his optics looking unnerved and slightly scared. Hook's hands paused over First Aid.

Straightening up, Hook looked at Orion and shook his head. "No. No, you haven't," he reassured, "Just wait for now. Ratchet should be back soon," Hook promised, his brothers quiet for the moment. This was still Orion. Young, unknowing and slightly confused by everything which was going on around him. Most importantly, clever.

Ratchet walked in to First Aid on a medical berth, out cold with Hook looking over him with Orion looking sheepish. Ratchet blinked slowly, moving over to his apprentice who was normally resilient against all things, both strange and serious. "Orion," He exhaled, knowing only one person could have really caused this in the young medic. "Explain please?"

"Orion worked out he's a reformatted mech because he remembers how he died. He doesn't remember who he was though," Hook commented softly.

"Op-Orion never died," Ratchet frowned, looking at the young mech who was swinging his legs. "You confirmed to him that he was reformatted without warning the rest of us?" he demanded.

"I did die. I felt it," Orion argued, pouting, "Anyway, it's not that hard to work out when you have the facts." He sniffed.

"Like what?" challenged Ratchet, sending red alerts out to the base. Orion knew he was reformatted but not who he was. Several pings came back, including Prowl who was already on his way to them. They needed damage control and they needed it quick before too much of Orion's former life came to life.

"None of you know where Vector Stigma is, do you?" Orion asked dryly.

"Its…" Ratchet trailed off, "It's connected to the Well of Allsparks."

"Though tunnels which only priests of Primus have access too. Given you all hate Primus, somehow I doubt you know the way. Which only leaves one way to get to Vector Stigma. Though the front door. Which is in?" Orion led, his tone brattish and almost condescendingly.

Both Hook and Ratchet looked at each other helplessly as they realised they didn't know. "Wait, Primus? You know about Primus?"

"Of course I know about Primus! I'm designed for the Hall of Records, sparks which second to only Priests when it comes to matters of the afterlife," Orion frowned, as both Ratchet and Hook looked at him blankly. "The archive and the great temples have always been strongly connected to each other. If a priest loses his way, often he becomes an archivist and sometimes archivist sparks are too priest like for their own good and go into the clergy. We're on the same caste level. Or were." Orion trailed off, "I guess now is different."

"The priests and the archivists were very private. I doubt many knew that outside of the groups," Prowl stated from the door, having arrived as Orion had given his explanation about how he had known about Primus. "Where is Vector Stigma?" Prowl asked, "Where is it that you knew you were not one of its mechs?" He demanded.

Orion looked directly at Prowl, his optics cold and said one name which made perfect sense in a strange sort of way. There was only one place no one had been since they had restarted rebuilding Cybertron. Mostly because the acid storms had all centred there, making it far too dangerous a place to travel too.

Kaon.

Optimus Prime grinned grimly as Prowl collapsed, Ratchet rushing to him. That was enough waves caused for one day.

A/N: not too quick I hope for Orion to regain memories in their eyes, though they still don't know Op is back. I figured Optimus would enjoy playing with them.
