A very moving story dealing with "The Rookies" and their kindness to a mentally retarded young man and the sister who takes care of him. I saw this as a boy and, just over thirty years later, still remember it. Mark Slade is very effective in the title role of this episode. His shyness at being quizzed by Kate Jackson when she is tutoring him, calling her "Miss Jill" is touching and not cloying. The actress playing Cliffy's sister (guessing from the IMDb cast list is that it is Tyne Daly) also delivers a strong performance. At one point she breaks down, confessing to Jill how difficult the sacrifice of being Cliffy's caretaker has been, and how she longs "to be held and comforted, instead of being the one who holds and comforts" was especially powerful. Here is hoping that this episode may one day be available on DVD.
