ATDTDA (2): Disconnection begins ... (53.35)

[Tim Strzechowski]

"The frontier ends and disconnection begins.  Cause and effect?  How the dickens do I know? [...] But you could feel it, unmistakeably, like a divide, where you knew you could stand and piss would flow two ways at once" (pp. 53-4).
 
 

I sense parallels here between the beginnings of "disconnections" and Slothrop's fragmentation late in GR.
 

Likewise, I feel a sense of the "divide" experienced/sought in M&D.
 

What is the relationship between "disconnection" and the ultimate connections we find between past and present in P's canon?
