The Blacklist showrunner John Eisendrath discusses if the show will ever reveal Red's identity. Ever since its debut in 2013, the NBC crime thriller has maintained an air of mystery around Raymond "Red" Reddington (James Spader). Although it's been a difficult balance to strike throughout the show's long run, The Blacklist has managed thanks to the strength of Spader's performance and the occasional hints offered. It's been implied that Red is actually Katarina Rostova, the biological mother of Liz (Megan Boone), who had facial reconstruction surgery to change their appearance. However, there hasn't been confirmation.

In comments shared with TVLine, showrunner John Eisendrath offered a clarifying answer about The Blacklist's biggest mystery. His quote is included below:

Here’s my answer: If it’s up to me, you will know exactly who he is. If you don’t know in the end, you’ll know that someone else overruled me.
