A year before the Flu, Arthur and Clark have dinner in London. By this point, Arthur has a son with his second wife (Elizabeth Colton) and he has just been served divorce papers by his third wife. He tells Clark that Elizabeth is taking their son and moving to Israel. During the dinner, Clark gets the feeling that Arthur is performing.
Here we see Elizabeth’s desire to move to a city with history playing out: she has taken their son to Israel. We also note art spilling over into life, as Clark can’t tell if Arthur is being genuine or performing some version of himself, acting instead of really being there as an earnest human.
