Trion smiled softly by his former students words. “That is most excellent to hear, Optimus. Surly now the future has become a bright for you and the others,” he said.
"I certainly hope so, Alpha Trion. I hope that I can provide a better future for our kind… it is all I can do to make amends… to try and repair the bonds among all Cybertronians. If that is even possible now, the war has divided our people so greatly for eons. Rebuilding the planet is one task, but reforging the bonds of mecha that have been fighting for so long? How do I possibly do so?"
/at this point he was just venting his uncertainties to the master archivist, he did not feel comfortable voicing such things to others. They would say it would be alright and believe in him, which he did not mind, he just wanted to get it all out and not be looked up to fix it but to ask for help/
"I lead the reconstruction effort to try and restore the planet’s surface. It will take much time but I know that we can do it once more mecha come."
Bumblebee stabbed Megatron through the spark…

You can make Orion!Pax/Megatron fanfics all you want, but I believe this is when Orion’s innocence was taken away. That guilt he carries as a prime shows here - you can see how painful it is when he kills something, even if it was in self defense. Because he lacks the power of the Matrix here, he doesn’t know how to hide it yet.
And that’s what makes this truly horrifying. This scene shows his first bloodshed as Orion, and the pain and guilt behind it.
