Major spoilers below for anyone who hasn't yet watched The Blacklist's midseason premiere, titled "Ruin."
Blacklist fans knew that the back half of Season 5 was going to be strikingly different from the show's past, with Liz facing a life without Tom after waking up from an extended coma. While I don't know that many people predicted she would immediately go on a self-exiled, cold-weather killing spree, that's exactly what happened, though the men Liz killed definitely deserved it. Regardless of how viewers reacted to Liz's continued evolution, actress Megan Boone is downright enthusiastic about these big changes.
My condolences to any diehard fans who were hoping that the largely standalone midseason premiere was more of an exception than Liz's new approach to life. The days of Liz (or Elizabeth, I guess) feeling vulnerable are over, at least when she's not around Tom's grave, and we're likely going to see the character continuing her dark descent for months to come. After all, she's got some pretty devious genetic material coursing through her veins, and being like Red may not be something Liz directly strives for, but she's getting there pretty quickly.
Even if taking down dangerous threats wasn't a major point of comparison between Liz and Red, what about how she passed Agnes on to her Tom's mother? That may have initially seemed like either a harsh move by the grieving mother, or a simple way for the show to put the young child on the sidelines, but as as Megan Boone put it to TVGuide, giving up a child to someone else is very much in line with what Red did with Liz. So she was basically just living up to her bloodline.
Even though Liz may be moving forward with her adjusted personality traits, the character isn't necessarily doing it with a clear conscience just yet. But taking control of her life and her future in this way will mentally open Liz up to start letting go of some of the self-blame she's carried for all these years. In Boone's words:
The midseason finale set up the Ian Garvey arc, and Megan Boone teased that character's story will guide The Blacklist through the rest of Season 5, with some big revelations coming. But sadly, the actress still doesn't appear to know what all those bones are about. Unless, of course, Boone shares her TV character's penchant for keeping secrets. [Rubs chin thoughtfully]
