Many thanks to our justly-feted El Misterioso for the captivating cameo portrait of handsome, attractive Chris Collins (portrayed by the late, much-lamented Don Briscoe).
In our time, Julia had learned [spoiler] that Chris Jennings actually was a descendent of Quentin Collins, and thus a Collins in his own right. It was cool that Chris' Parallel Time counterpart actually bore the name of Collins.[/spoiler]
Too bad that Don had to leave the series very abruptly soon after this episode was taped due to health concerns.
