Fringe 5x09 - "Black Blotter" (Commentary, Discussion & Spoilers!)
While Olivia and a recently-recovered Peter investigate a mysterious signal coming from a forest, Walter uses LSD to try and recall his memories of his plan to defeat the Observers.
Is anyone else besides me laughing already at the prospect of seeing Walter do drugs again?
And I'm going to go out on a limb here and speculate that the mysterious signals from the forest have something to do with that radio from the pocket universe... And that the infamous 'numbers stations' are connected to it. I may be wrong about that last part, but I just can't shake the feeling.
