'Fringe' is a JJ Abrams production, as is 'Lost', and we've seen a connection between the two earlier this season, with Olivia holding Oceanic tickets.
In this past week's episode ("Bad Dreams"), Agent Olivia Dunham stopped into a shop to buy a box of "No-Sleep", the Toobworld equivalent to "No-Doze". I grabbed the image, flipped it, reversed it, enlarged it, enhanced and clarified it, but just couldn't make out the small print on the side of the box. But it damned well looked like one of the main words began with a "W".
So it made me wonder if perhaps, maybe, just maybe, No-Sleep could be a product of Widmore Laboratories?
Just sayin', is all......
