Well, it begins with Doc smoking a White Owl cigar loaded up with
sinsemilla and Scott remembering that he "saw that Coy." (297)
This "send[s] Doc off down the Toilet of Memory" to Larry and Shasta
munching dogs and listening to jams and to his eyeballing the Rides
purchased by studio musicians some of which may be Repoed by people
like Larry and the People he's been Turned by and works for. Is it
ironic that Larry might threaten a studio musician with a syringe? I
think it is. In any event, typical of Pynchon's paranoid prose, the
cars connect to the film Vertigo (1958). Yet another film produced
from a French detective novel. Yet another novel produced not by a
single author but by a prolific collaboration. Does this mean
anything? Don't know. Maybe the Owl Cigar, machine produced and cheap
is contrasted with the sinsemilla too? In any event, from the toilet
memory and Vertigo we jump to Doc's parting from Coy and the guilt Doc
feels because he's supposed to be helping and working for  Coy and for
Hope, but hasn't made much progress or put much effort into this job.
So Doc, stoned,  heads down to the Lighthouse, following Scott's lead,
and finds Coy there. We see the scene through Doc's POV, and he is
stoned. At times we get dialogue between Doc and Coy with the common
tags, like Doc said and Coy said.  At times there is dialogue between
Coy and the people running him and there are no tags. The narrator
here, slides into free indirect style. Is this the narrator you say is
reliable?
