Meredith loves working on her hubby’s clinical trial to cure Alzheimer’s. So it’s a bit of shock when the Chief asks her to head up another clinical trial to cure diabetes based on research found in her mother’s journals. The decision as to which groundbreaking endeavor to choose is put on hold when Meredith and Lexie learn their dad has come into the hospital with abdominal pains and a 20-something tattooed girlfriend.
Bailey doesn’t believe Thatcher’s condition is a result of liver rejection. His new lady love, Dani, realizes the pains occur whenever he drinks lots of liquids. This info helps the docs determine that he has a treatable kidney stone. But it doesn’t look like anything will cure Lexie’s growing loathing of Dani. She wants her sis to join her in the hate-fest, but Mer can’t go there. She tells Lexie to grow up and just let their dad be happy.
