Bernard kill both his mother and a neighbor with a frying pan before being killed by Catherine herself in pre-self defense.
Jerry, the "Asperger's"-addled attorney took Shirley hostage after being denied partnership he was a secondary character for much of the series' run before become a full regular cast member in, I believe, the second to the last episode.
BL was a good, fun, show but mostly made that way between The Shat and Alan Shore. Alan Shore delivered some of the series' best moments and closing arguments. If there's one flaw this show had it was its revolving door of secondary cast members. Brad Chase and some pretty young blond woman whose name escapes me were there for much of the series' early run before disappearing, Candice Bergen and John Laroquette were made regular cast members at various points and they did very good jobs (the former latched on in the first season, the latter fairly late in the series) but there were a large numbers of secondary cast members.
There was Lake Bell's character, the young black woman, the dickish young white guy (both were recent graduate of law school and did mostly busy-body work without having any "cases" they took part in but were also open-credits featured cast members), the portly cross-dressing guy, the tight-assed blond woman, the gorgeous dark-haired woman who was a lover of Alan's early on, the skeletal, "pretty-ish" English woman who was another lover of Alan's, and others I know I'm forgetting.
There was a lot of cast on this show. I'd dare say the main cast is never the same from season-to-season. Aside form Alan Shore, Denny Crane, Shirley Schmidtt, and John Laroquette's characters people went in and off of this shore more than they did on ER.
It's really sort-of silly.
But a very fun show if for nothing else for The Shat and his relationship with Alan and many of Alan's closing arguments, although everyone else gets their fair share of them too.
