There are a lot of interesting stories worth-exploring in The Blacklist season 8 once it arrives on NBC. There are also plenty of questions when it comes to the future of some characters, especially Raymond Reddington. The major concern here is his health as it looks like it's seemingly deteriorating.

Reddington's condition has been hinted several times and many were worried about his fate in the future. The Blacklist season 8 may now address his health, given that his sickness is obviously taking a toll on him and it's getting worse.

Dembe is worried about Reddington's condition, while Liz founds herself rushing to his care. But despite the obvious clues about his health, he doesn't want to reveal what's really happening with him. In an interview with TVLine, series creator Jon Bokenkamp has something to say when it comes to this matter.

Bokenkamp said they've already hinted Reddington's health issues over the past few seasons. Yet, this is something the character is avoiding or denying -- he doesn't want to tell anyone what's wrong with him. But then, the people around his life are concerned about it.

While Reddington is not a weak man, his health issues aren't going to go away just like that. He won't be able to deny what's going on with him, especially when things get even worse. Bokenkamp said that Reddington's condition is something they've absolutely want to explore in The Blacklist season 8.

Perhaps, one of the main reasons why he wants to hide his condition is to make sure those who are after him wouldn't exploit this as his weakness. That's also the reason why he only has a few people on his end. The more people know about his sickness, the more people may want to destroy him.

Meanwhile, Katarina Rostova is still part of the upcoming The Blacklist season 8. There are a lot of mysteries when it comes to this character, especially her status. Moving forward, the series could further explore her motive, as well as her plans.

It's yet to be seen how long she'll be part of the next installment, but it looks like she's still a big part of the story. She may play out a huge role in the showdown between Reddington and Liz -- something that could play out an extended period of time.

As per CarterMatt, Katarina's arc will likely last within the first few episodes of The Blacklist season 8. The series may not want to see Reddington and Liz at odds through the entire season, as there could be other villains arriving along the way.
