Summary
As he thought about it, he realized a few things. First, that the destines of Mobius and the Mushroom World would be forever entwined because their worlds were forever entwined—and the destiny of their heroes was similar, no matter which way he picked. Secondly: despite his strength, and the strength of his brother, Mario and Peach wanted them to stay, not because they were helpless, but because they wanted them to grow up safe.
And thirdly, he really didn’t mind that prospect.
Somehow that was the strangest part about this.

Summary
Against every instinct in Sonic's core, he had stayed in Camelot even after Caliburn's reveal. Shouldered the weight of this stupid crown for as long as he thought he could. It was beginning to weigh on him horribly, and people were beginning to notice. And then Gawain showed up with a girl in tow, proclaiming her to be his betrothed.
He didn’t think he had been terrible at this whole rulership gig, especially for someone who didn’t want it in the first place. But this? This was the last straw. Still, it wasn’t like he could just leave—his knights would need guidance, and the people would need a protector, and Guinevere…
…well. Maybe, in ways that his court hadn’t expected, she was exactly what he needed.
(Or: Arthur meets Guinevere. Sonic’s determined to make sure this doesn’t go as written)

Summary
The fall? That’s the easy part.
Do you trust others enough to catch you?
Do you trust yourself enough to jump?Or:
Sonic once told Tails, “it’s okay if you still need help sometimes; that’s just part of growing up.”
Mario and Peach seem intent on making him eat those words.- Words:
