Ellen calls on Lorraine, who is terribly sick. Ellen sees that Catherine Moray (Kim Huffman) - who was also present at the political celebration - wanted to talk to David. Catherine may donate some money to the university in terms of a grant, which would give an edge to David over his competitors. Catherine is amazed at how civil Ellen is towards David. Ellen is worried about Lorraine's sickness. Graham is also worried about the deteriorating state of Lorraine, so he calls Ellen. Lorraine suffers from the same ulcers in the legs which Ellen used to have. All her other symptoms are exactly the same as Ellen's. However, David tells Ellen not to tell Lorraine anything. David phones Ellen to tell her that he is going to take Graham and Lorraine to a hospital in Mexico which is very quiet; without phones or an internet connection.
Dr Addington phones Ellen - selenium (a very toxic element) could have been the cause of her symptoms. Ellen tells David, but he dismisses her.
