Homeland Sunday at 10 p.m., Showtime

This has been a crazy season — fast-paced, well-acted, and sloppy in the plot department. What will happen to Damian Lewis’s Brody in the finale? It’s hard to imagine how the writers could write him out of this corner without turning “Homeland” into a fantasy series. But will they kill him off? And if they do, will the series become about an internal affairs issue, with Carrie (Claire Danes, left) and Saul (Mandy Patinkin, right) on the outside trying to expose someone such as David as a terrorist?
