Irreversible -- the decision -- yet there Harvey goes on halcyon stroll, thinking there's a hue that's 1 part Anna's blue blood and 1 part his simmering red that would be appeasing to third-party perspective.
Their blood has mixed before; instead of rich violet, the colors oiled and watered -- staggered -- too proud to blend, and yet there Harvey goes into the park, listening to the children laugh and he thinks how a violet child would suit him and Anna well.
Worse -- the hope -- than any wear either person has suffered, hope has a funny way of keeping one suspended in the air, and a funnier way of chaining two together that hope in the same vain.
