I think one cannot deny that Sonic and Elise had that romance thing going on whether you like it or not.

Well, yes. But that's a fan theory. What I'm talking about is the development of the two characters. My theory says that they were probably the same character initially. The games were in development around the same time, how could they not see the similarities? They somehow 'fixed' this problem by pushing Blaze into Silver's storyline with no background regarding being a princess or guardian of the Sol Emeralds. There must be a reason why they did that just for one game, right?

I think it was because of Elise. They have the same concept. The only difference is that Elise had a monster inside her and Blaze didn't.
