Pete Thornton's vision problems were written into the show because Dana Elcar himself was suffering from the same problem in real life. Elcar would eventually go blind.
John Considine who wrote this script, had just co-starred in the previously broadcast, "There But for the Grace".
After this episode, Dana Elcar (Pete Thornton) would only appear in six of the remaining eighteen episodes of the series, mainly due to his battle with glaucoma.
