A few weeks ago, the 4th Doctor’s introductory tale ROBOT gave Doctor Who Club its first look this year at Sarah Jane Smith.  Played by Elisabeth Sladen, she has, time & again, proven herself to be the most popular companion in Doctor Who history.  She originally traveled with the 3rd & 4th Doctors (as well returning for The Five Doctors & her first spin-off series, K9 and Company) but this week’s episode — SCHOOL REUNION — returns her to the Doctor Who universe full time, along with another iconic character:  K9, voiced by John Lesson. Together they are re-united with David Tennant’s 10th Doctor, which would eventually lead to her second spin-off show, THE SARAH JANE ADVENTURES (which Doctor Who Club also occasionally re-visits).  This week, Doctor Who Club re-lives Sarah’s joyful & poignant return to the small screen.
