1 of 10
Millions of fans are obsessing about the new hit medical drama, Grey's Anatomy. On May 14, 2006, 22 million people tuned in to watch the jaw-dropping season finale of Grey's, which focuses on the personal and professional lives of five surgical interns, their supervisors and patients.

All season, fans have wondered what will happen to Dr. Meredith Grey (second from left), an intern who's involved in a steamy love triangle with Dr. Derek Shepherd and his wife, Addison (third and fourth from left). To complicate things even further, Meredith gets romantically involved with her dog's vet, Finn.

Will Meredith Grey choose Dr. Shepherd, played by Patrick Dempsey, or Finn, played by Chris O'Donnell?
