This Sunday's episode of "Homeland" is already being labeled as one of the "top five best episodes ever" by TV Line. The site received some intel about episode nine, titled "Three's Something Else Going On," and said "much of the focus is on the prisoner swap - Saul in exchange for those half-dozen terrorists in South Africa - and Carrie's familiar feeling that something is amiss."

"I'm not going to tell you if her suspicions turn out to be correct, but I will tell you to make sure the edge of the seat is comfortable, because you'll be fused to it during much of the hour," TV Line added.

It was previously revealed that the season four finale was going to be a real tear-jerker and fans may be in for a surprising death. Last week, TV Line reported that one of their sources in South Africa - where "Homeland" is filming - said "the show recently shot an elaborate funeral sequence at a chapel in Cape Town presumably to air in the season finale."

Of course, it's not clear who could be killed but fans seem to be convinced that Saul Quinn, Lockhart or Haqqani could be axed from the series. In even better "Homeland" news, Showtime announced earlier this week that the show was picked up for a fifth season with 12 episodes.

The network is also bringing back the hot new show "The Affair" for a second season.

"In its fourth season, 'Homeland' had brilliantly reinvented itself. It continues to capture the attention of a devoted fan base, and has provided an enviable platform for the successful launch of 'The Affair,'" said Donovan Nevins, President of Showtime Networks. "With thought-provoking, timely and addictive storylines, both series have been embraced, dissected and much debated week after week. We're excited to see more from these compelling shows in 2015."
