So, we know that Classic Sonic learned how to boost from his future self. I guess we can qualify it as a bootstrap paradox now. So, how do you think Sonic originally got the idea of that move ? Who really composed Beethoven's fifth ?
Well... if you mean Sonic himself then it probably was just a continuous cycle of teaching and learning. I've seen that sort of thing to an extreme in a movie before so it does happen (it was the weirdest movie I had ever seen o_o )
