In the season 10 opener, Rob (
Don Grady), Katie (
Tina Cole) and the triplets have moved into their own place. Katie feels that Steve (
Fred MacMurray) needs a woman in his life, so she arranges a blind date, Millicent Sawyer (
Elaine Devry), for him. Meanwhile, Ernie (
Barry Livingston) has a problem in school so his dad has to meet with his teacher, Barbara Harper (
Beverly Garland). Rob and Katie are worried how to break it to Steve that his blind date, Millicent, isn't interested in him, but Steve has already become smitten with Ernie's teacher, Barbara.
