The man transformed himself into a tiger. Watch till the end

Seattle Grace Hospital welcomed a new group of interns, five friends who had graduated from medical school together. They needed to compete for official resident positions through outstanding performance. At the beginning of their time at the hospital, Meredith was shocked to discover that the man she had a one-night stand with at a bar the previous night was Derek Shepherd, a neurosurgeon. Their complicated relationship began there. Cristina attracted the attention of cardiothoracic surgeon Preston Burke, as they were both equally proud and ambitious. George secretly loved Meredith. Beautiful Izzie started gossiping right away. The one-year internship was destined to be filled with high-pressure competition and hormones.
