After Tails fought Exeller, Eggman and Knuckles...he ended up at Mountain Peak...now questioning what to do.

Tails the Fox: "Is it Over? The timeline didn't reset. Will my friends still be dead? WHAT HAVE I DONE!? I DIDN'T LISTEN TO MYSELF FROM ANOTHER DIMENSION! MY FRIENDS ARE STILL DEAD!"

Tails started crying for a bit then stopped.

Tails the Fox: "No. The demon is defeated. Sonic would of been proud of me. I should find the others now."

Exeller is still alive since Tails only defeated the clone.
