SPOILERS: I couldn’t use the “Sensitivity” storyline because the exact functioning of Dave’s brain ended up being enormously important to the larger story arc of Narbonic. There’s a lot of stuff I wrote early on that had to be jettisoned in service to the plot.
At one point I loved both of these storylines a bunch. They say in writing you have to kill your darlings. These are a couple of dead darlings.
