Sider's House
"Yes... YES!" - Shouted Sider, smiling.
He clearly hadn't changed. The Spark was still within him, the inspiration to create, to think, to conceive of things that couldn't be in ways that were not possible. His mind still twirled with grandiose plans, without ever considering what could happen if he were successful.
"Matt? Quick question. That did prove your theory, but doesn't it run the risk of exploding if actually energized?"
Good thing he had Riruka, then.
"Er..." - He said, blushing - "Technically... Yes, but..."
"No buts. We're using the dimensional space you created for this." - Said Riruka.
"Fine..." - Said Sider, blushing. She kept him safe. Safe was boring, but he liked that she kept him safe.
Over half the mad scientists Sider knew of had changed back. As it turned out, being a mad scientist isn't necessarily good for flesh and blood people that could well be maimed or killed by a mishap. However, Riruka was there, which - Sider knew for a fact after examining some alternate probabilities with his machinery - was what kept him sane enough to remain a mad scientist and not self-destruct.
Sider chuckled to himself. Some nine months after a fight he and his machines fought for the world, against the undescribable. One year or so after... After being normal, in a normal world, no magic, no mad science.
No Riruka.
Sider smiled at what it all had become. I earned it, he thought, I did fight for the world... - And, indeed, he had.
Sider looked at a pile of scrap metal and some fuses, and saw again. He saw something wondrous, something magnificent and that would help humanity. The spark within him flared up as he pictured it, planning and making calculations in his head as he drew on a blackboard, Riruka smirking slightly as she watched him.
"New plans?" - She asked.
He didn't answer, which Riruka rightly took to mean yes.
Sider was, once again, doing Science and planning and creating, already building his next machine with the aid of other pieces he had already prepared, his mind filled with dreams of a better tomorrow, of an utopia, the spark within him propelling him forward and up, more and more and more, seeking perfection, never finding it, and enjoying the trip immensely anyways, a goal clear in mind that he might or not achieve for the betterment of humanity, for science!
And Riruka was always there, by his side, to remind him of the human element, to keep things safe, to ensure he did not get lost in it all, yet very much a scientist herself and every bit his equal in normal science. He could not have asked for a better assistant. Neither could she.
Life was good.
