"The Ghost Network" also included their quest to explain seemingly impossible and weird phenomena through a real scientific explanation from Walter's past research.

It received mixed reviews, with many believing the show to be finally finding its legs, while others worried over the ongoing formulaic storylines featured in each episode.

A man named Roy McComb (Zak Orth) confesses to his priest that he sees visions of bad things, including a bus where everyone is going to die.

In an interrogation, Roy tells Charlie (Kirk Acevedo) he's been receiving his visions for nine months, roughly when they began seeing Pattern-related attacks.

This leads Walter to recall he and his old lab partner William Bell had conducted research on creating a "Ghost Network" to secretly communicate messages from one person to another in an otherwise undetectable frequency range.

Phillip Broyles (Lance Reddick) secretly gives the disc to Nina for analysis, while Roy is sent home, as they believe he will no longer see visions because the Ghost Network has been compromised.

[2] The writers had the idea for a couple of weeks of Olivia walking into an apartment and discovering walls covered with drawings of events that "no man could possibly have known about".

They wanted to take "urban myths or legends of strange events" and come up with a fringe science equivalent; this led them to creating the story of Roy, a man with seemingly "psychic" abilities, which they then expanded by offering a real scientific explanation in the form of Walter's past research.

Early in the show's creation the writers were trying to figure out what Fringe could be, and ultimately chose "big crazy event[s]" at the start of each episode that would catapult its plot and drive its characters.

By the end of the episode, the mystery becomes extremely compelling and finally Fringe hits that special place of TV series addiction reserved for shows like LOST and Battlestar Galactica.

Murray thought the climax was "so exciting" that he was willing "to forgive the fact that this is the third week in a row that Walter's big idea has involved some kind of communication with the unconscious".

[9] IGN's Travis Fickett rated it 7.5/10, writing that he thought it was a solid episode because the "characters are coming together nicely, the story is better than last week's – but already it seems the show is hitting a formula".

[7] Writing for Mania.com, Stephen Lackey thought that though the episode wasn't perfect, Fringe had finally seemed to hit its stride, as its "mix of humor and darker storytelling... is starting to come together nicely".

Lackey concluded his review by expressing his "excitement" at watching Fringe get better and better, and thought the show could become the best new series of the year if it continued to improve with each episode.
