Hal's confession to Mario — "It’s been like forty hours without…"
‘It’s been like forty hours without Bob Hope and already I’m bats inside and I can’t sleep without more of the horror-show dreams. I feel like I’m stuck halfway down a chimney.’ […] It seems different with me, Boo. I feel a hole. It’s going to be a huge hole, in a month. A way more than Hal-sized hole.’ […] ‘And the hole’s going to get a little bigger every day until I fly apart in different directions. I’ll fly apart in midair. I’ll fly apart in the Lung, or at Tucson at 200 degrees in front of all these people who knew Himself and think I’m different. Whom I’ve lied to, and liked it. It’ll all come out anyway, clean pee or no.’
