Sophia's new friend, Alvin Newcastle, who is a retiree who lives at the Ocean Mist Retirement hotel, is also an authorized security guard there, which may have been his vocation in his earlier years. The two have a common accquaintance, a Molly Feinstein, who lives there at the hotel. The two immediately bond, but, as the friendship begins to develop upon their initial meeting, the old fellow's behavior becomes erratic, as Sophia reminds him of his wife Edna as he has trouble remembering her name.
When Alvin is late in meeting Sophia at the beachside boardwalk, he, who was supposed to meet her at 9:00am, arrives an hour late after missing the bus he usually takes on the way, as he blames it on "that dumb-ass driver who went the wrong way!" Later on, Sophia learns that Alvin suffers from Alzheimer's Disease. Later on, Dorothy meets Alvin's daughter Sandra (Janet MacLachlan), who confides in Dorothy that it's a daily struggle with looking after her father, who, after once wandering off at one time, forced her to take off of her job, in taking a leave of absence, to look after him. Alvin eventually winds up getting moved to New York City at the behest of his daughter, and it's later revealed at episode's end that he will be living with his nephew, who's a doctor who knows how to take special care of Alvin. Saddened by his condition, Sophia, in conversing with Dorothy at the boardwalk, wonders if Alvin will still remember her name, let alone the time they spent together sitting on the boardwalk.
