This is an AU where the Doctor didn't regenerate after Tranzalore. Instead, he is back to his youthfull self. He's spending time with Clara a lot more often. A new story begins as one ends. This is a Whouffle fanfiction and is T for future writing.

This is a crossover of Doctor Who and Sonic the Hedgehog. I do not own Doctor Who and Sonic the Hedgehog. This is the comic series of Sonic the Hedgehog, not the game verse. The Doctor travels to Mobius, not knowing he's in a different dimension. What makes it worse, everyone is confusing him for someone named Silver. They are saying that he looks just like him.
