Homeland‘s recent ratings growth continued Sunday with a penultimate episode that delivered the thriller’s biggest audience of the season. Showtime’s espionage drama had 2.1 million viewers — the eighth consecutive season high for the show. It also marks Showtime’s most-watched telecast of the year.

Homeland has enjoyed a creative revival in season four, though hasn’t been able to recapture its peak viewership — its biggest number remains the third season finale (2.4 million). But since Sunday’s episode was higher than last year’s second-to-last episode, perhaps we’ll see a new all-time record set during next week’s finale.

Showtime’s The Affair also continued to grow, with 837,000 viewers. That’s up 10 percent for the week and up 65 percent from its season premiere. Though obviously a lot lower than its lead-in, networks look for growth and at least the extramarital drama is headed in the right direction.
