You was walking in the alleyway until you see Sonic...feasting on his own best friend...Tails, ripping his flesh, eating it and so on..until Sonic turns his head and looked at you with blood dripping down his face, body parts over his face and more gorey stuff on his face..

Sonic: hello~ darling...~ would you like to have some of my..dinner...?~

he holds Tail's guts to your face to see if you would eat it..and his breath was rotten and disgusting with teeth and blood on it...
