S04E10 finale
Anything for blood.
Mark and his 12-year-old daughter's lives were changed forever 10 years earlier when she was turned into a vampire. Locked in at age 12, perhaps forever, Eleanor lives a closed-in life, able to go out only at night, while her father does his best to provide her with the minimal amount of human blood she needs to stay alive.
Mark moves quickly to clean up a mess, and Zeke gets roped in to help. Claire is hit with a major setback at the lab and Matthew proposes a solution. Naomi makes a devastating discovery that confirms her worst fears.
