By Season 4 the show had really hit its stride. The Blanche vs Sophia battle here for Fidel is filled with the kind of one liners that are the trademark of the series.
Sophia's comments can sometimes come off as a little mean but here we finally get to see someone giving Blanche what she so richly deserves. When she calls her a fifty year old mattress it's really funny. Sophia works her magic and outwits Blanche as only she can.
The side story doesn't cut it. After a silly Hitler joke, Dorothy pronounces that Rose is a high school graduate. Way too unrealistic, even for the Golden Girls.
