More than anything, I want their friendship to survive even if a relationship is not to be. After chasing a serial killer throughout the course of the season, John Moore (Luke Evans) and Sara Howard (Dakota Fanning) finally confronted their feelings for each other. The Alienist: Angel of Darkness airs two episodes back-to-back Sundays at 9 It's something that viewers have been waiting for, and needless to say, it went well beyond their expectations. I’m okay if this was it for John and Sara as far as the romance goes, because it was done with great love and affection. Libby got away, the baby was found, and more importantly, for fans, John Moore (Luke Evans) and Sara Howard (Dakota Fanning) had not just a kiss, but a full-blown love scene. There has been much back-and-forth on this, as Sara had spent most of the season denying her feelings for him because she was afraid of putting it into words.
