Question about Bess/Phyllis relationship
So I watched the first 3 seasons on hulu. They stopped at Season 3 and YouTube picks up at Season 5 (Season 4 blocked by Fox). My question, in the first 3 seasons, Phyllis treats Bess like a "little adult". She even says this on a couple of occassions. In season 4 however, there is an episode where Mary is watching Bess while Lars ad Phyllis are out of town. Bess is 16 yrs old and wants to stay out till 11:30, past her 10:30 curfew. Mary is adamant that Phyllis would NOT approve of this.
What happened in Season 4 to make them start treating Bess like a child and did Sue Ellen get introduced in Season 4? It's like she just "appears" as a regular in Season 5.
