Tails went to Green Hill Zone to find Sonic and once he got there...it was full of dead animals and He noticed blood on Sonic's hands so he flew away and got caught and teleported to a burning angel island and kept running until he bumped into you...Exeller passed you both losing Tails.

Tails the Fox: "AH! DON'T HURT ME PLEASE! I-I-...wait your not Sonic."
