Brace yourself, Blacklist fans. The season 3 finale is primed to blow you away.

It is time for the truth. As Tom (Ryan Eggold), Red (James Spader), and the FBI conclude the investigation into Lizzie's (Megan Boone) death, viewers will get more answers than they bargained for.

Titled "Alexander Kirk: Conclusion," episode 23 will aquatint fans with a character they've been itching to encounter since the series premiere.

"The finale's going to be a lot of fun," Eggold teased during the Wednesday edition of the Today show. "What do I say? We're going to meet a new character that I think we've wanted to meet from the very beginning of the season - of the series, rather."

What?! Who could the actor be referring to? There are several mysterious characters that have bedeviled viewers since The Blacklist's inception, and narrowing it down to just one is nearly impossible. To make matters worse, Eggold does not want to be the one to ruin the surprise.

"It's somebody. I'll say it's somebody," the USC alumnus joked. "No, it's someone we've been wanting to know about since day one of the show, so that will be fun."

Liz's father? Liz's mother? Liz reincarnated (we doubt she died to begin with! Either that or we're in severe denial)? Every possibility is equally exciting. We're sure The Blacklist will leave Twitter buzzing as the summer hiatus begins, if not due to the newbie then certainly courtesy of an impending betrayal.

"As Reddington and the task force close in on the person responsible for Liz's death, a shocking betrayal leaves them racing to save one of their own," NBC teased.
