Well yes look if anda see Sonic and the black night Sonic saves Percevel(Blaze)and the sword of Sonic said"Save the hug and kisses for later" and Blaze blush and Sonic berkata "Are anda jealous atau something" This proof that Sonic loves Blaze not Amy
I think in the "Sonic Rush" series he does. And in the first one they were holding hands for a long time at the end. I think I heard from somewhere that they may have kissed but it's uncertain. I don't know but I really like them together! =3
