Well, you know the Sonic fandom. XD There are actually more Sonic and Amy shippers than Sonic and Blaze. The Sonic fandom... is messed up, rlly. Though to answer your question, I think they shouldn't. Personally.
Totally... I mean, the Sonic series NEEDS more furry romance scenes in it. Personally I always thought that Knuckles and Rouge should get married too, they are so totally into each other! Maybe I should email Sega and give them my suggestions.
