Clementine (Gracie Dzienny) may have one of history’s most difficult deliveries, and not just because of her own physiology, in the new episode "Cradles and Graves." As the birth of her child nears, toxic spores surround her and most of the rest of the team, effectively trapping them inside their plane. Hilary Jardine and Robin Thomas continue their guest roles. James Wolk, Billy Burke, Kristen Connolly, Nonso Anozie and Alyssa Diaz also star.
