Nancy Travis Checks into GREY’S ANATOMY January 27, 2011 Grey's Anatomy, News Nancy Travis will guest star in an upcoming episode of GREY’S ANATOMY. TV Guide reports that Travis will be checking into Seattle Grace as Allison, an Alzheimer’s patient participating in Derek’s (Patrick Dempsey) clinical trial. Because Allison’s ten year old son mothers her more than she is able to mother him, Dr. Stark (Peter MacNicol) will want to call in social services. It’s not known when the episode will air. Travis, an actress I always thought would be a much bigger star, is best known for her roles in ‘So I Married an Axe Murderer’ and ‘Three Men and a Baby.’ She also starred in the TV series The Bill Engvall Show, Becker, and-my favorite– Almost Perfect. Grey’s Anatomy airs on ABC Thursdays at 9pm eastern/8pm central.
