The surgery that George was attempting was an appendectomy. After this incident, George was frequently called "007" (lisence to kill). During the whole first season of Grey's Anatomy, George has had a crush on fellow intern, Dr. Meredith Grey. On top of that, George also lives in the same house as her along with Dr. Izzie Stevens, another intern.

Even though we find out later that he had a crush on Meredith, George still has a relationship with Nurse Olivia Harper.
