George Hopper was SPC. Aaron Hawthorne's supervising physician. Upon finding Hawthorne didn't respond well to the stage four inhibitor treatment, Dr. Hopper was given the orders to euthanize his patient but was denied by Dr. Fyodor Malikov. On September 27th, 1952, Hopper inoculated Hawthorne with the stage five inhibitor treatment which yielded positive results.
