Eric Dane, beloved by fans around the world for his role as McSteamy on Grey's Anatomy, was spotted this week in a wheelchair at a Washington, DC airport - and the sighting marked a visible and emotional turn in his harrowing battle with ALS. The 52-year-old actor, who first publicly revealed his diagnosis with the terminal disease in April, appeared noticeably frail while sitting in the wheelchair as an aide helped him through the terminal. For longtime admirers of the charismatic actor, the sight was difficult to process.
