As for Ryan Eggold, it has been stated in the past that Tom Keen will return to The Blacklist.
With The Blacklist: Redemption officially done, it will be interesting to see how the series attempts to tie in Tom’s story from the canceled series and possibly incorporate some of the other characters.
That doesn’t seem likely, considering Season 1 ended with Tom unwittingly putting his evil father in charge of Halcyon, and the receiving proof his father is evil.
With the renewal of The Blacklist coming down yesterday, the odds are in favor of the writers having time to rework any ideas Season 5 had in place, as well as securing Eggold’s role in the upcoming season.
