Mark Sloan X OC Season 1-? How can one choice change it all? We all know how Mark Sloan's story ended but what if Ellis Grey had two daughters by Richard. TWINS. How will Mark Sloan's story change with Jordan in his life? Read to find out. This is my first story and I'm horrible at summaries but I make it up by updating multiple times a week!! DISCLAIMER I do NOT own any Grey's Anatomy characters but the O/C's in my book are mine!
