A brief glimpse of the plot

I've seen it! There is a plot in Infinite Jest!

As we follow Madame Psychosis through her slum walk, she stops at the end of a row of drug dealers. There, standing before her is a cutout figure of a man in a wheelchair looking like he's been captured in the middle of a tremendous laugh. The cutout holds a TP cartridge which bears no label whatsoever. Just as the cartridge the medical attache received had no label (aside from the mysterious "Happy Anniversary" note).

Further, the cutout is definitely modelled on Marathe, the Quebecois quadruple agent. What's unclear, though, is if it's just his likeness and therefore something set up by the Wheelchair Assassins, or if it's based on a photo of Marathe. In the latter case, it could be that he has viewed the mysterious cartridge and succumbed to its horribly hilarious charms.

In any case, the cartridge's appearing in various places like this and the intrigues involving radical Quebec groups suggest some sort of thriller-type plot. It's in here somewhere.

Also quite mysteriously, in the middle of Madame Psychosis' walk, we're treated to a list of all of the subsidized years involved in the book. It definitely has meaning, but why it is where it is (and not in another endnote) is unclear.
