Now in its eighth season, this diabolically twisty crime thriller keeps coming up with ways to bring main characters into intense confrontations wherein it seems unlikely more than one player will live to fight another day. That's certainly been true for this show's two central characters, master criminal Raymond "Red" Reddington (James Spader) and FBI special agent Elizabeth Keen (Megan Boone). So just because tonight's new episode finds Liz hellbent on getting revenge on Reddington, nothing fatally irreversible is likely to ensue.
