Spoiler Alert: Fringe S04E03

While this episode was pretty interesting, a little mix of E.T.: The Extra-Terrestrial (the child's psychic connection to the fungus), Star Trek (the needs of the many outweigh the needs of the few, or the one), and Care Bears (the child doesn't feel like anyone cares for him), there wasn't a whole lot of development of the central season-long story arcs.

1. Walter and Olivia's Insane Outing

Not only is Walter bound to his laboratory and his living quarters, but he has to have continuing analysis by approved therapists to assure that he can remain out in the world. The appearance of Dr. Sindel casts a very troubling light on an upcoming problem. Walter needs to, at the very least, appear sane, or else he is going to be carted back to the looney bin. Of course, he's seeing his erased adult son Peter in reflective surfaces and hearing him everywhere, so we've got some sort of problem here.

The problem is only exacerbated by the fact that Olivia has been seeing the same person, Peter, in her dreams. She presents Walter with a picture that she drew of this "Man in the Mirror," a picture that she has been running through facial recognition programs.

The episode ends with Walter exclaiming, "We have to find him." And it sounds like the beginning of an adventure. But will this adventure end with Walter, and possibly Olivia also, in the mental asylum?

2. Aaron

This child, Aaron, who established the psychic link with the murderous fungus, has been alone for some time. Nothing is said about his parents. It is said that he has been staying with a neighbor for a while, but that the neighbor ignores him. He has absolutely nowhere to go and nobody to care for him. But Walter has a hole in his heart where once Peter lives, and Walter promises to care for Aaron.

At the end, Aaron is carted off to the hospital. We are left wondering whether Aaron will actually join the regular cast of the show, which seems to be what Walter promised, or whether he will be brushed off and only serve the purpose of making this particular episode work. I hope that he becomes a regular, and I think it is likely considering the mystery regarding his loneliness.

See you next time.
