Fringe Spoilers: Another "Observer" Episode

On April 7 we definitely get an "Observer?" episode of Fringe. We say Observer with a question mark because the team finds a bald, silent and seemingly empathic child who never eats or pees and who looks a lot like an Observer mini-me, but whose, uh, peccadilloes could be explained by perfectly reasonable science. Then again, this is Fringe, so he's got to be a wee Observer...right?
