Homeland.  Sixth season of the perpetually tense spy drama ends with an episode titled "America First." What I want to know: Will Carrie (Claire Danes) get her daughter back? Will President-elect Elizabeth Keane (Elizabeth Marvel) ever be sworn in? Or will the fake-news forces and the "dark state" others allied against her somehow win? 9 p.m. Sunday, Showtime.

Sesame Street.  As the long-running children's program introduces Julia, a Muppet with autism, to the cast, HBO is making the episode available to PBS stations on the same day, without  the usual nine-month delay.  8 a.m. Monday, HBO, and 10:30 a.m. Monday, WHYY12.

Note: Third-season premiere runs about an hour, 10 minutes. 10 p.m. Monday, AMC.

Switched at Birth. After five seasons, the Peabody Award-winning drama that celebrated deaf culture through the story of two girls, one of them deaf, who were raised in each other's families, comes to an end in an emotional 91-minute finale that hits all the right notes. 9 p.m. Tuesday, Freeform.
