Harry and Erica ran in from the beach and had a very romantic evening with no power. Even though Harry likes to sleep alone, he comes to Erica's room and say he wants to try to sleep with her. In the morning, they are on opposite sides of the bed. When did the switch take place? Lovemaking happened earlier, so that probably did not take place during the night because the next morning, they wake up late and comment about sleeping a full eight hours.
