Jason and the team are in a military hospital, almost certainly Landstuhl Regional Medical Center as they are said to be in Germany. Run by the U.S. Army, it is the largest American hospital outside the United States. The doctor treating Jason tells him that he highly recommends that Jason undergo further testing to determine if he has traumatic brain injury, before something catastrophic happens. However as a military doctor he can order Jason to undergo further testing. A physician in the military would not ignore a patient potentially having TBI, especially when that patient is the leader of a Tier One SMU.
