Fans gathered for the panel for NBC's drama "The Blacklist" on Saturday received black fedoras, in honor of the character played by James Spader.
On "The Blacklist," Spader is Raymond "Red" Reddington, a fedora-wearing former fugitive who turns himself in to be an informant. The catch: He will only deal with rookie agent Elizabeth, played by Megan Boone.
As season one unfolded, speculation grew that Red could be Elizabeth's father.
On Saturday's panel, Spader, along with executive producers Jon Bokenkamp and John Eisendrath, wouldn't say much about the true nature of their relationship.
Bokenkamp acknowledged "that question is central to the conceit of the show" but said they wouldn't provide an answer right then.
Spader said he believes what's important is the character's relationship in present day.
There was also a casting announcement: Mary-Louise Parker has a recurring role with ties to Reddington.
"The Blacklist" returns for its second season Sept. 22.
