Fans of Fringe are wondering when there will be another Observer-based episode of the show.

According to Kristin from E! Online, that may take place when the series returns from hiatus on April 7.

How come we cannot say for certain? Because the installment titled "Inner Child" focuses on a a bald, silent and seemingly empathic young boy. He never eats or pees - and he looks a lot like a mini Observer. What does this mean for the big picture?

Come on. This is Fringe. We're not gonna try to guess.
