Mrs. Slocombe had multiple personality disorder.
- When she is "unanimous",she means all the personalities are in agreement,instead of just a majority.
Mrs. Slocombe is an Auror.That's why her hair changes color.
- Do you mean Auror (wizard cop) or Metamorphmagus (Tonks)?
Mr. Humphries is Mr. Grainger's illegitimate son (or at least Mr. Grainger thinks he is).Remember when Mr. Grainger mentioned that he once "got a girl in trouble"? Nothing more is said about this during his time on the show, but later we had an episode with Mr. Humphries thinking that Old Mr. Grace was his father and his mother basically admitting that she didn't know who his father really was. Given that his mother was the one who helped Humphries get the job with the firm in the first place, it's also likely that she prevailed upon Mr. Grainger to keep an eye on "their boy" throughout his career. And Grainger shows FAR more affection for Humphries than anyone else on the floor, and seems to take his quirks and affectations in stride. Since Lloyd and Croft used the same plot contrivance on Dad's Army (with Sgt. Wilson and Pike), it's safe to assume that this idea would have been explored more thoroughly if Arthur Brough hadn't passed on after Series Five.
- Wow, very interesting! Except that Mrs. Humphries did have three guesses as to who the father was: A commando who parachuted into the backyard, a milkman who got kicked in the head by his horse, or a passenger of a "tunnel of love" ride that she got trapped in a tunnel with. Seeing that Grainger was with the firm all his life, he most certainly wasn't the milkman. He could have been the commando in the war although with that past, I don't see him playing second fiddle to war-faker Peacock all those years, so I very much doubt it. However, if Grainger was who she was trapped in the tunnel of love with, then, yes, he could be Humphries father.
Departments at the store were consolidated over the years.When the show began, Mrs. Slocombe and Miss Brahms worked in "Ladies' Intimate Apparel" and there were several other female sales staff on the floor. By the end of the series, the two were the only women visible and the department had expanded to sell outerwear. Given the pathologically frugal nature of the store's management and a passing mention in the first episode of Grace and Favour that the main characters were the only employees left when the store closed, it's likely that the departments were merged during the series as a cost-cutting measure.
