Big Sky killed off what could have been a long-running big bad of the series with Legarski’s death, which leaves viewers with Ronald.
Instead, after some serious introspection, a suspicion that his memories were returning, and a realization about what her husband had planned to do to her with his hammer, Merrilee beat her husband to death with his own hammer in his hospital bed.
Legarski met his doom in “Let It Be Him,” but not due to his body failing after Cassie’s gunshot or Ronald breaking into the hospital to silence him or anything that viewers might have come to expect from this series.
