Did You Know?


The show "Zoom" that Astrid downloads for Walter towards the end of the episode is a children's educational TV show that was filmed in Boston, Massachusetts- the same city where Fringe is supposed to take place See more »


When Walter decides they need to take LSD for the journey to work, he asks Astrid to help mix up "2000 milligrams" of LSD, which is insane. He probably meant 2000 micrograms. A fairly large does for one person would be 450mcg so, 2000mg/3/450mcg =~1.5 million times the recommended dose, which would likely cause permanent brain damage if it didn't kill them. See more »


Dr. William Bell: Please tell Walter that I knew the dog wouldn't hunt.

Very Solid Entry Some Clever Ideas
16 April 2011 | by Traxman15See all my reviews

Hello Once Again: This is the Most Intriguing Episode of Fringe so far, well Done, some Very Imaginative Story Ideas--Good Pacing--Well Written--Great Acting--All In All It Bodes Very Well For the Upcoming Wind Up of this the 3rd Season! When are the Renewals for Fox Announced for Next Season? I Really Hope They Get Away from the Current Trend of Having Olivia in Trouble all the time, it is Getting Stretched Way Too Extreme, and Got Old Way Back in the Middle of Season Two! Does anyone else find these types of Episode Make you want to Yawn? The Next 2 I think will Determine if the Series Makes it any Further! I Don't see How they Could Fumble It Now--Seems to be heading into some Very Original Story Telling! Let's Hope That all the People Following this Will Watch and Push it's Numbers Way Over The Top!

Cheers T:
