The story of a changeling walking along in the Everfree Forest. He finds himself in Ponyville where he remembers the words of his lost younger brother.
"Changelings and Ponies can co-exist, without the need for us to hide ourselves."
Truly his brother was mad...but what if he wasn't? The unknown wanderer decides to test the theory for himself; by taking the form of an infant and hiding away with a family of strangers. If ponies really could accept Changelings as they were, then surely they would not ignore a cry for help; no matter who it came from.
