“The Blacklist” Season 4 premieres tonight. But while waiting for the new season of the NBC series, here’s a quick rundown of what went happened in “The Blacklist” Season 3 finale to refresh your memory.

“The Blacklist” Season 3 finale, titled “Alexander Kirk: Conclusion,” dropped some shocking revelations, including the answer to one question fans have been asking since Raymond “Red” Reddington (James Spader) entered Elizabeth Keen’s (Megan Boone) life: who is Liz’s real father? It turns out Red’s longtime nemesis Alexander Kirk was actually Liz’s long-lost father Constantine Rosov (Ulrich Thomsen)...or so he claims.

Before Kirk’s big confession, Red, still reeling from the loss of Liz, proceeded with his plan to take down Kirk and take revenge for Liz’s death. Red stole his contribution to presidential hopeful Senator Robert Diaz’s (Benito Martinez) campaign and manipulated the latter into telling everyone that he will be going after Kirk for buying oil from terrorists and smuggling it into the country.

After framing his nemesis for financing terrorists, Red then set out to fulfill his real objective, which was to kill Kirk. Cooper (Harry Lennix) didn’t stop him, even telling Red, “I know so many zealots, men and women, who choose a side, an ideology by which to interpret the world. But to get up every single day and do the hard work of deciding what to believe; what’s right today; when to stand up or stand down… that’s courage. It’s been a privilege to see first-hand why the people you lead love you the way you do.” On the other hand, Ressler (Diego Klattenhoff) couldn’t morally let Red kill Kirk in front of him, so he tried to stop him. In the end, Red didn’t get his revenge, and Kirk managed to escape.

While this was going down, Tom (Ryan Eggold) managed to escape from Mr. Kaplan’s (Susan Blommaert) watchful eye with his daughter Agnes in a getaway car. They headed to where a private plane was waiting to take them to Cuba. However, Kirk was on their tail and also headed to Baracoa, Cuba. Red found out about Kirk’s trip, so he asked Aram (Amir Arison) to find out who else flew to Cuba within the past six hours, before looking for the man who loaned Tom the plane. When he found him, Red dangled the man — who was one of his associates — 40 feet over a driving range, forcing him to confess that it was Mr. Kaplan who asked for the plane for Tom’s escape and that he thought it was Red’s idea.

When Red went to confront Mr. Kaplan about her betrayal, the biggest shocker of “The Blacklist” Season 3 all came tumbling out: Liz was actually alive. Kaplan told him that she planned all of it in order to protect Liz and her daughter and to keep her away from Kirk’s clutches. “What do you want to know, Raymond?” she said. “If I’m sorry? Yes. I’m sorry you weren’t more honest with Elizabeth from the beginning. I’m sorry that you wanted to know her so desperately that you convinced yourself we could keep her safe. I couldn’t sit back and watch you make the same mistake with Agnes. I didn’t betray you. I did what I’ve always done: I protected you — this time, from yourself.”

However, it seems that it was all for naught because Kirk found Liz and Agnes anyway. When Tom arrived at their home in Cuba, he was attacked, and by the time Red and Kaplan got there, there was no sign of any of the Keens.

Meanwhile, Liz — who supposedly died after a car crash — has been abducted by Kirk and tied up in a chair in one of his hideouts. She demanded to know where her daughter is, but instead Kirk revealed something else: that’s he’s been waiting 25 years for this moment and that his real name is Constantine Rosov.

But is Kirk telling the truth about being Liz’s father? What is his motive for approaching Liz after more than 20 years? Find out what the answers to all your questions are when “The Blacklist” Season 4 premieres Thursday, Sept. 22 at 9 p.m. ET on NBC.
