Lots of firsts this week.   It’s our first viewing this year of Tom Baker’s titanic 4th Doctor, Lalla Ward’s impish Romana, and their indefatigable robot dog, K9.  FULL CIRCLE also marks the debut of Matthew Waterhouse as new companion Adric.  Finally, this week’s episodes mark the first full-on shift in tone for the series in 1980/81, as it begins the transition to the new 5th Doctor era that was just about to begin.  This week, our intrepid group of Whovians get to re-live all of it once again.  NOTE:  because of the PD DAY this Friday and EASTER the following week, this is first of two consecutive weeks that we will be meeting on THURSDAY!
