No, Zachary Quinto has not purchased a time machine, though he may have access to the next best thing. Who Do You Think You Are? is an Emmy-award winning docuseries where special celebrity guests go on a poignant search to trace their family tree with the help of genealogists, historians and experts. In an exclusive clip of the show, Quinto reviews letters published by his great great grandfather and discovers a message chillingly similar to a catchphrase of an iconic role of Quinto’s: beloved Star Trek character Spock.
