In the Last Episode Sonic Dies! He was killed by Mephiles. His whole plan was to kill Sonic so Elise would cry. If Elise crys than Iblis will be sent free! Thats why Mephiles wanted Silver to kill Sonic! If Mephiles fuses with Iblis, than they will become SOLARIS! I'm not telling you any more about the Last Episode. Let's just say that you'll be happy in the end....
