Sally asks Rob if he has a single brother, and Rob says that his brother is married. However, Stacey, Rob's brother (whom we meet later in the season) is not married and indeed does develop an on-again/off-again relationship with Sally.
Laura's hair when dyed blonde is much shorter than her actual hair is (obviously a wig). When her dyed hair is first seen, it only reaches down about half-way of her neck. When Millie is in the process of dyeing it back to brunette and she walks out of the bedroom, her hair reaches down past her shoulders.
Sally talks about her boyfriend "Woodward" Glemshire (spelling) who has a mother issue. She then states Woodwards mother has set her up with "Herman". In later episodes she is dating Herman Glemshire.
