The CIA also recruited Gregory House on the case and he was introduced to Curtis by Dr. Samira Terzi. House decided to get off on a bad foot by telling Curtis he recognized him from his book, then telling him that he used it to prop up one of the legs on his piano. House also blew off Curtis's suggestion that John was suffering from horse chestnut poisoning. However, Dr. Terzi went with Curtis's suggestion that John was suffering from radiation sickness.
