Supernatural (Friday, 9/8c, The CW)
It's angels in America time again, as Castiel wings it back to Earth to help the brothers solve a case of police murders that seems to hark back to the plagues of Egypt. While there, Cas reveals that Heaven in in post-apocalyptic chaos and God's weapons have been stolen. (Ergo, the search for the staff of Moses.) And while seeking the supernatural thief, they confront an old enemy.

Saturday Night Live (Saturday, 11:30/10:30c, NBC)
Can you imagine Jane Lynch sharing sketch time with the brilliant Kristen Wiig? We can, too, which is why our expectations are high as the Emmy-winning Glee scene-stealer hosts SNL for the first time. We can only hope she gets better material than the writers delivered to last week's first-timer, Bryan Cranston, a brilliant talent left stranded by acres of unfunny. Come on, SNL, give us something to sing about, or Sue Sylvester will have fresh meat for her operatic rants.

Boardwalk Empire (Sunday, 9/8c, HBO)
As on-the-lam Jimmy seeks new purpose in Chicago with the help of Al Capone, Margaret indulges in romantic fantasy, captivated by headlines about Anastasia, the woman rumored to be the sole surviving member of the massacred Russian royal family. Margaret has her own fairy-tale moment at a lavish party thrown by Nucky, but the real world circa 1920 has a way of intruding on happily-ever-afters.

Dexter (Sunday, 9/8c, Showtime)
Dexter is finally putting his life back in order, hiring a nanny for baby Harrison and getting back to his life's mission: killing other killers. His new prey is a sanitation worker (Shawn Hatosy) specializing in — get this — roadkill. As Dexter goes undercover, he's told, "You gotta be OK around dead things." Not really a problem for Dexter Morgan. Some shocking twists ahead in this hour, the strongest so far this season.
