WARNING! This article contains spoilers for The Blacklist season 8 finale. Read at your own risk.

The Blacklist season 9 comes with a lot of twists and turns once it arrives on NBC. The eighth installment ended in May 2021 and left a massive cliffhanger – the death of Liz Keen (Megan Boone). Before she died, Raymond Reddington (James Spader) handed her a letter but the content was never disclosed.

In the upcoming The Blacklist season 9, one of the major mysteries may revolve around the letter. At the end of season 8, Reddington gave Liz a letter and he wanted her to read it – but only after she killed him. Although it's unknown what was written on it, the content could be all about his true identity.

Reddington asked Liz to kill him first before reading the letter. But, in an unexpected turn of events, Liz was shot by Neville Townsend’s (Reg Rogers) right-hand man. This is a shocking twist in the season 8 finale, given that Boone’s character was one of the major players in the series.

Things may potentially change entering The Blacklist season 9. The letter will remain part of the story, but it is uncertain how it’s going to play out now that Liz is dead. Since she hasn’t read the letter, another person – possibly Dembe (Hisham Tawfiq) – may read it.

Ever since the series started, there are a lot of questions surrounding Reddington. There have been several theories on the character, with some believing that the real Raymond Reddington was dead and the current one was actually a double agent.

Meanwhile, it is unlikely that Boone will reprise her role of Liz in The Blacklist season 9. The character’s journey seemingly concluded at the end of season 8, and her possible return might only be shown in the flashback scenes. Also, the actress’ departure has been planned all along.

Liz headed into the darker path in the previous season, hinting that her death is just around the corner. Throughout the eighth installment, she teamed up with unlikely allies – including Townsend – which have led her to her death.

Liz’s major goal is to uncover Reddington’s real identity and find out his secrets. She’s been trying to take down his former partner, as well as bring down his empire once and for all. However, she won’t be able to do any of these now that she’s dead.

The Blacklist season 9 official release date has not been set as of this writing.
