“Homeland" Season 5 is just on the horizon, and while Showtime fans are undoubtedly looking forward to catching up with Carrie, Saul and Quinn, there may be some confusion heading into the 2015 installment. Before Season 5, episode 1, titled "Separation Anxiety,” premieres Sunday, here’s a refresher of what happened during last year’s season closer.

In Season 4, episode 12, “Long Time Coming,” Carrie (Claire Danes) has just returned to the U.S. While working as station chief in Islamabad she received word that her father, Frank (James Rebhorn), had passed away. In a state of despair over her dad’s death and her failure to capture terrorist Haissam Haqqani (Numan Acar), Carrie is in mourning, but she isn’t alone.

After fearing the worst, Carrie learns that Peter Quinn (Rupert Friend) is not only safe, but he's also back from Islamabad to support her. Quinn shows up to Carrie’s father's funeral, and the two reconnect, eventually sharing a steamy kiss. Quinn begs Carrie to leave the CIA in pursuit of a normal life, but she refuses, claiming her bipolar disorder will be the end of them.

During a spontaneous visit with her long-lost mom (Victoria Clark), Carrie realizes that she can have a successful relationship with Quinn after her mom informs her that her dad’s bipolar condition was not what resulted in their divorce. But when Carrie tries to reach Quinn to tell him the good news, she can’t get ahold of him.

Meanwhile, Saul decides to meet up with Dar Adal (F. Murray Abraham), a potentially two-timing CIA agent, to discuss his desired return to the CIA. Dar says he can put Saul on the short list of replacements for failed CIA director Andrew Lockhart (Tracy Letts) under one condition: He requests that Saul remove Haqqani, with whom Dar was seen riding in a car in Islamabad one episode prior, from the kill list.

In an effort to contact Quinn, Carrie reaches out to Dar for intel. When she meets up with him, he teases her about Quinn’s whereabouts, saying he’s overseas fulfilling a mission. When Carrie doesn’t get the direct answer she’s seeking, she threatens to expose his secret connection to Haqqani. Dar calmly tells her to speak to Saul about her assumptions. Carrie then finds Saul sitting peacefully in Dar’s backyard, leaving viewers questioning Saul’s motives.

Season 4 ends with a shot of Carrie driving away from Dar’s home.

Season 5 will pick up over two years after the events in last year's finale. Viewers will catch up with Carrie living in Berlin working as the head of a security for a German philanthropist. Quinn and Saul will return with a newfound -- yet secret -- partnership. And it looks like Saul got what he wanted; he’s back in the CIA.
