As of 1-28-12 the IMDb info is not complete: Looks like Currie Graham (Of Stargate: The Ark of Truth) guest-stars as the father of a girl, Alexis Raich? as "Emily", who has an extraordinary gift, revealed in this Fringe Ep's incredibly blunt Teaser. The Procedural Case of this ep, investigating a girl who can see the future, occurs right after The Observer's Visit to Olivia in the Opera House, and so Orange 'Verse Broyles wants to overly protect her, to Olivia's chagrin- But the two things, the Observer's Visit and Emily's Talent both seem to be inextricably related.
This ep goes back to why I love this show, Walter of course explains the girl's gift in a Fringe Science way. One thing that departs Fringe from X-Files, is that each conundrum is soundly based on some science that has been at least partially proved.
What makes this Ep great is that we finally have Peter Bishop working with the Orange 'Verse Fringe Team, and so he is no longer being avoided by Walter and they are realizing that they work well together. This is the same discovery that took us the first five or six of season 1's eps to discover - That Peter and Peter Only, can speak Walter.
There is a scene, the "Money Shot" I mention - where Emily is being guided through her vision by Walter, this is one of the best effects shots I've ever seen on Network TV, it's Feature Film quality, and knowing that Fringe has had budget cuts this year, amazing that they were able to pull this off- But when it comes down to it, Fringe does not need to dazzle us with CGI shots, the story holds our interest. But I like that once in a while, we get a treat like this. So Far this year, we get the Transparent Skin of the new Shapeshifters, the "Invisible Guy" from "Wallflower", and now this. I just hope they did not blow all of their special effects budget on this one shot!
