The Republic of Sarah

CW | 9:00 pm

When unseasonably warm weather quickly melts the snow from the recent blizzard, Greylock faces the threat of massive flooding in the new episode "From Simple Sources." Realizing the community could be completely underwater in a matter of hours, Sarah (Stella Baker) is forced to ask for help from Paul (guest star Xander Berkeley), the last person she wants to rely on. Meanwhile, Bella and Tyler (Landry Bender, Forrest Goodluck) take a big step in their relationship, and Grover's (Ian Duff) therapist urges him to embrace what makes him happy.
