Why do people like these pairings?
Swift says: "Personality-wise this is where I'd say Sam/Sonic comes into play. It's another case
of rivalries turn into friendship, which has already happened with Sam and Sonic. Sam disliked Sonic for stealing his title
as 'the fastest thing alive' and vowed to beat Sonic. He competed against him a lot in Sonic X, looking to beat him and regain
his title, though he revealed in episode 42, he knew he could never beat Sonic, but he still tries anyway. That's basically
one important thing Sam and Sonic have in common; speed. Sam loves moving fast and so does Sonic. They enjoy the thrill of
the competition against each other and as time went on in SX, they developed a pretty good friendship, though they were still
rivals in speed. Anyway, they both have a similar outlook on life too."
