Cupcakes...

Some times they set my teeth on edge - other times, they help me control the chaos.

I'm not like other ponies. I see their friendship, I just can't feel their friendship.
So I blend in.
Hide my dark passenger.

Sometimes ponies do really bad things, but escape the system, escape justice. Celestia can't catch them...

...but I can.
