I started watching S1 again today and got through the first 3 discs so far. Hubby came home from work and started watching with me. We still laugh at stuff. I pointed out an Observer that he did see in one episode and I spotted one of the Butterfly glyphs in the background in a different episode. He didn't see that one either.
This was on Twitter. Fringe fans are dedicated to the point that a glance at a pic gets noticed four years after the show ends
And of course I consider us part of that fandom
