Spencer is incredibly, undeservedly pleased with himself. He really didn't do much besides pick a hill and yell out a time, but he's sitting pretty at the top of the hill like he's overseeing the culmination of a great and magnificent project. His legs are crossed underneath him and his cheeks are flushed from the cold and happiness. When someone sits beside him, he fishes a small flask of rum (the one Heathcliff gave him) out of his coat and wiggles it at them in a "want some?" gesture. Despite this, Spencer himself seems pretty sober.
